Silicosis, radon, and lung cancer risk in Ontario miners
Uranium miners are at an increased risk of developing lung cancer. This is generally attributable to exposure to radon. However, miners are also exposed to silica, classified by IARC as a possible human carcinogen. In a study of lung cancer risk in 328 miners with silicosis, which included a small number of uranium miners (23 subjects), it was found that the radon risk factor decreased when lung cancer risk was adjusted for the presence of silicosis. Smoking is also an important risk factor, but it was not feasible to include smoking in the statistical models. The results for the radon risk factors are, however, uncertain because of the small number of uranium miners included in the sample. Additional studies of this factor are considered warranted.

The occurrence of sister chromatid exchanges in lymphocytes of radon-exposed underground ore miners
Frequencies of sister chromatid exchanges (SCE) were investigated in peripheral blood samples taken from underground uranium miners exposed to various levels of radon and from unexposed controls. Six exposure groups were identified according to the level of exposure. While no general tendency was observed in change of SCE frequencies with increasing radon exposure, significant differences were found between certain groups of miners. The findings are discussed with respect to the opportunity for biological monitoring of radon exposed persons.

Development of a long-term personal radon monitor
A personal radon monitor based on track etch technology and housed in a watch casing was developed and field tested. The monitors were worn continuously for two months by 49 subjects. Standard REM AT-100 radon monitors were placed in the homes of each subject and local background radon levels were used to estimate exposure for time spent away from home. A good correlation was obtained between the standard and watch monitors. The watch monitors were well received by participants and are potentially useful for domestic and occupational settings.

Radon in the working environment: Position report
Radon i arbetsmiljön: Lägesrapport [in Swedish]
Attention has been devoted for several decades to health risks associated with exposure to radon in various environments. Further indications of such risks have recently appeared for the rather modest exposure in dwellings. These data, together with the development of international recommendations and a new Swedish action programme, prompted the Criteria Group for Physical Risk Factors at the National Institute of Occupational Health to issue this position report. The Criteria Group came to the following conclusions: actions taken to reduce the radon level in work environments should be given a high priority; the action programme of the Swedish Radiation Protection Institute (SSI) for dwellings and certain work premises provides a basis for this work; an effective programme includes a thorough survey of different workplaces, especially within areas at risk for geological reasons, and specific proposals for remedial measures; education and information are also important parts of such a programme; a reevaluation of exposure limits for mines should be undertaken, on the basis of the recommendations issued by the International Commission on Radiological Protection (ICRP) and forthcoming directives from the European Union (EU).

Dose-response relationship for radiation carcinogenesis in the low-dose region
The present knowledge of the effects of low-level radiation gained in in-vitro and epidemiological studies is reviewed. Included are the studies of the effects of radon in homes. The in-vitro studies provide evidence that low-level radiation greatly enhances the efficiency of DNA repair. The epidemiological studies of people exposed to low levels of radiation have shown that cancer incidence is not higher than in the general population. The linear, no-threshold, dose-response relationship used to predict cancer incidence caused by exposure to high radiation doses does not apply for exposure to low doses of radiation.

Prevention of lung cancer through the use of knowledge on asbestos and other work-related causes - Norwegian experiences
This review attempts to estimate the contribution of different known work-related causes of lung cancer among Norwegian men in order to predict the potential of prevention of work-related cases. The presented estimates are based on data from epidemiological studies made in Norway, but may be of significance for other countries with a similar work-force structure. Over the past decade asbestos-related lung cancer appears to have contributed about two-thirds of the lung cancers that have been related to work exposure in Norway. Compounds of nickel and chromium have also contributed, although to a lesser extent, along with exposure to polycyclic aromatic hydrocarbons, radon daughters, seafaring work, and other, less significant specific and non-specific determinants of lung cancer. Prevention would be fostered by synergic actions.

Lung cancer among tin miners in Southeast China: Silica exposure, silicosis and cigarette smoking
Incidence of lung cancer was studied among miners in Dachang tin mine (China), known to have relatively high levels of suspended dust (silica and other potential carcinogens) and low radon levels. Among the risk factors for excess mortality from lung cancer, only the years spent drilling underground and the cumulative smoking index (product of daily cigarette consumption and number of years smoking) were independent contributors to risk; no interaction between the two was observed. The presence of silicosis did not contribute to predicting the risk independently of the years spent underground.

A retrospective mortality study of workers exposed to arsenic in a gold mine and refinery in France
In a mortality study among employees of a French gold mining and refining company, a twofold excess of lung cancer was found among both miners and smelters, mainly concentrated among workers who had experienced exposure to past levels of arsenic, radon and silica. The consistency of the results in the mine and the refinery are suggestive of a carcinogenic risk from both soluble and insoluble arsenic, although the potential role of other factors cannot be dismissed.

Lung cancer mortality and airways obstruction among metal miners exposed to silica and low levels of radon daughters
A study of miners in two Sardinian metal mines showed an increased mortality for nonmalignant chronic respiratory diseases in both mines. Among underground miners from mine A (low silica and high radon levels), there was a slight excess of lung cancer mortality which increased with duration of underground employment; highest lung cancer mortality was observed in underground miners with an obstructive ventilatory impairment. Deaths from lung cancer in mine B (higher silica and lower radon levels) were less than expected. Results suggest a slight association between lung cancer mortality and exposure to radon daughters. Impaired pulmonary function may be an independent predictor of lung cancer and an important risk factor.

Removal of radon daughter aerosols from mine air by filtration
Respirator filters and filtering facepieces were tested for penetration of radon daughter aerosols; tests were carried out in a fluorspar mine and in the laboratory. Respirators with a filtration efficiency high enough for them to be considered suitable for use against toxic dusts generally reduced radon daughter levels by 90% or more, although nuisance dust masks were ineffective. Comparison between on-site tests and tests with a standard aerosol showed that respirators that satisfy an existing standard could be expected to give reasonable protection against radon daughters.

Mortality of iron miners in Lorraine (France) - Relations between lung function and respiratory symptoms and subsequent mortality
An increased mortality from lung and stomach cancer was found in previous studies on Lorraine iron miners. In this study the cohort included 1,178 workers selected at random from all the 5,300 working miners aged between 35 and 55 at the start of the follow-up period, which ranged from 1975 to 1985. Occupational exposures and tobacco consumption, lung function tests and respiratory symptoms were assessed for each subject in 1975, 1980 and 1985. The study confirmed the excess of lung and of stomach cancer. It is considered that the risk of lung cancer in the Lorraine iron miners was mainly due to dust, diesel engine exhaust fumes and explosives although the role of low exposure to radon daughters could not be totally excluded.

Risk comparisons between limit values for ionizing radiation, PAH, and benzene in Sweden
The background of regulatory limit values for carcinogens is discussed and exemplified with the ambient and occupational air pollutants benzene and polycyclic aromatic hydrocarbons (especially benzo[a]pyrene, BaP), ionizing radiation and radon. The estimated cancer risks at different limit values are compared, as is the estimated number of cancer cases annually due to existing pollutant levels. Although the individual lifetime cancer risks are much higher at the occupational limit values for benzene and BaP than what is recommended for the general public, the estimated number of cancer cases annually is lower at existing pollutant levels. The individual cancer risk at the occupational limit for ionizing radiation is comparable to the occupational cancer risk with BaP, but higher than the one for benzene. The estimated number of cancer cases annually due to radiation is low and comparable to the estimated number due to the chemical air pollutants discussed.

Ontario gold miners with lung cancer - Occupational exposure assessment in establishing work relatedness
Determination of the work-relatedness of the compensation claims of Ontario gold miners who had primary lung cancer could not be based upon any strict occupational criteria. However, a relationship between exposure to silica, arsenic, and radon progeny was derived from results of the epidemiological studies. A retrospective occupational exposure assessment of silica dust, arsenic and radon decay products was made in 11 individual cases presented in this paper. The exposure parameters provided persuasive evidence when the data were consistent with the key epidemiological findings, e.g. the miner's age at first exposure, length of dusty exposure, and latency.

Researching health risks
The Office of Technology Assessment of the US Congress analyzed the nature and organization of federally funded research on health risk assessment in terms of the resources and priorities of the agencies concerned (the National Institute for Occupational Safety and Health, among others), the linkage of research to decision-making and the limits of research-based information in making social policy. Assessment of the risks associated with radon exposure was taken as a case study. Promising areas for future research and factors of importance for successful assessment were identified. Risk assessment activities outside the USA were surveyed.

Video display terminals and radon
Recent reports indicate that video display terminals (VDTs) can collect radon daughters from the air. This occurs especially when they are turned off and may have negative electric fields which attract positively charged radioactive dust. Various techniques were evaluated for removing the gettered radioactivity while the video display terminal is both off and on. An evaluation was also made of what happens when the video display terminal is switched, thereby reversing the electric field near the screen. In addition, possible inhalation effects experienced by a video display terminal operator during field reversal were studied; it was found that although some radioactivity may be released during the cycle, room air currents redistribute it into the room with no detectable levels being inhaled by users.

Basic theory for the diffusive sampling of radon
From the closed-form solution of the Fickian equation describing the uptake of radon by a diffusive sampler, the following are calculated: (1) the optimal estimate of the time-weighted average radon concentration; (2) the effect of the geometry of the diffusive sampler on performance; (3) the maximum sampling time consistent with a predetermined maximum error in the estimated time-weighted average concentration of radon; and (4) the effects of temperature and pressure on the performance of the sampler. It is shown that the maximum sampling error can be greatly reduced by dividing the adsorbent bed into two layers placed in series and by using a weighted average of the uptakes on the two layers.

Skeletal 210Pb levels and lung cancer among radon-exposed tin miners in Southern China
A preliminary case-control study of 19 lung cancer cases over 55 years of age and 141 age-matched controls was carried out among underground tin miners exposed to 222Rn and its decay products. Radon exposure was estimated through measurement of 210Pb activity levels in the skull, and in working level months. There was a smooth gradient of lung cancer risk with categories of skeletal 210Pb level at time of last radon exposure; relative risks of 1.0, 2.9, 3.2, and 4.7 for categories <51.8, 51.8-77.7, 77.8-107.3, and >107.3Bq (<1,400, 1,400-2,099, 2,100-2,899, and >2,899pCi), respectively. Relative risks were unaffected by adjustment for exposure to arsenic in the mine or by adjustment for working level months. Risks also increased with cumulative working level month exposure, but the gradient of risk lessened after adjustment for exposure to arsenic. 210Pb, at the time of last radon exposure (p=0.13) and at the current 210Pb level (p=0.01), was not highly correlated with the working level month estimate.

A cohort study in Southern China of tin miners exposed to radon and radon decay products
The report is an historical cohort study of exposure to radioactive radon gas among Chinese tin miners. The cohort consists of 17,143 workers with 175,143 person-years of observation and 981 lung cancer events. The excess relative risk increased linearly with exposure, rising 0.6% per working level month (95% confidence interval [CI] = 0.4-0.8). Adjustment for exposure to arsenic dust, a known lung carcinogen, reduced the effect of radon exposure to 0.2% per working level month (95% CI = 0.1-0.2). The excess relative risk/working level month declined significantly with attained age and with radon exposure rate as measured by the cumulative working level month divided by duration of exposure. Lung cancer risk did not vary consistently with age at first radon exposure. A joint analysis of radon exposure and smoking status rejected both an additive and multiplicative association; the relationship was consistent with an intermediate association.

Radon exposure and cancers other than lung cancer among uranium miners in West Bohemia
Report on a site-specific cancer mortality study of 4,320 uranium miners in Western Bohemia (Czech Republic), who have been followed up for an average of 25 years, and among whom a 4-fold radon-related excess of lung cancer had already been established. For all cancers other than lung cancer the number of deaths was slightly greater than expected from national rates, but the increase was not statistically significant (O/E 1.11, 95% CI=0.98-1.24). There was no relationship between mortality on one hand, and duration of employment underground and cumulative radon (Rn) exposure on the other. There was a significant increase (unrelated to cumulative Rn exposure) in non-lung cancer mortality among men who started mining work aged under 25. Of the 28 site-specific cancers examined, significant increases were found for cancers of the liver (O/E=1.67) and gallbladder and extrahepatic bileducts (O/E=2.26, related to cumulative Rn exposure). There were no significant increases in overall mortality from multiple myeloma (O/E=1.08) and leukaemia (O/E=0.91), but mortality from these causes increased with cumulative Rn exposure and increased employment duration, respectively. Further research is needed to confirm any association between Rn exposure and cancers other than lung cancer.

Transformation of field monitoring results into miners' annual exposures to radon progeny
This paper presents a method for estimating the radiation hazard affecting miners, using the values of radon daughter concentration in the work environment. Measurements carried out in metal ore mines showed that seasonal changes in radon daughter concentration were the principal factor to be taken into consideration in the estimation of the hazard. These measurements also confirm the correctness of the method.

Silicosis and lung cancer in U.S. metal miners
The association between silicosis and lung cancer mortality was estimated in 9,912 (369 silicotics and 9,543 nonsilicotics) white male metal miners. These miners were examined by the U.S. Public Health Service during 1959-1961 and were followed through 1975. The ores that were mined consisted of copper, lead-zinc, iron, mercury, lead silver, gold and gold-silver, tungsten, and molybdenum. The standardized mortality ratio (SMR, U.S. white male rates) for lung cancer was 1.73 (95% CI: 0.94-2.90) in silicotics and 1.18 (95% CI: 0.98-1.42) in nonsilicotics. When lung cancer mortality between silicotics and nonsilicotics was compared, the age-adjusted rate ratio (95% CI) was 1.56 (0.91-2.68), and the age- and smoking adjusted rate ratio was 1.96 (0.98-3.67). Corresponding figures for miners who were employed in mines with low levels of radon exposure were 1.90 (0.98-3.67) and 2.59 (1.44-4.68), respectively. These findings indicate that lung cancer mortality risk was increased in silicotics, and this probably did not result from chance or bias. However, confounding from radon exposure could not be ruled out.

Diseases of uranium miners and other underground miners exposed to radon
In the United States, most underground uranium mines had shut down by the late 1980's but occupational exposure to radon daughters remains a concern for many other categories of underground miners and underground workers. Worldwide, uranium mining continues in Canada, South Africa, other African countries, and Australia. The paper outlines the relationship between exposure to radon daughters and dose to target cells in the respiratory tract. It summarises epidemiological studies of radon and lung cancer in miners and reviews three of the most recent risk models used to estimate the excess lifetime risk of lung cancer associated with radon daughter exposure. The paper concludes by outlining negative health effects other than lung cancer, including cancer at other sites, non-malignant respiratory disease, renal disease and reproductive outcomes.

A diagnostic centre was installed capable of monitoring several parameters, including air filtration and ventilation rates and the levels of indoor contaminants. The contaminants were measured as frequently as every 10 minutes at several locations; they include: carbon dioxide; carbon monoxide; respirable particulates; formaldehyde; radon; and volatile organic compounds (VOCs). There are at least 37 VOCs in the interior air. Although the levels of these compounds are below established limits, they are also compounds for which no extensive research has been done to establish irritant levels.

The environment and the lung: Changing perspectives
This paper discusses the changing focus across the century of public health concern and research in regard to environmental lung diseases. Broad groups of environmental agents that produce lung disease are considered along with the currently available evidence for several air pollutants selected to be illustrative of the changing emphasis of concern. These include asbestos, radon, environmental tobacco smoke, acidic aerosols, sulfur dioxide and oxidant pollutants, including ozone and nitrogen dioxide. In the persistent concerns about adverse effects of polluted air on the lung, the focus has shifted from avoiding clinical disease among highly exposed individuals to protecting the population from an unacceptable burden of risk.

Measurement systems and indices of miners' exposure to radon daughter products in the air of mines
This paper presents the classification of measurement systems that may be used for the assessment of miners' exposure to radiation in mines. The following systems are described: the Air Sampling System, the Environmental Control System, the Individual Dosimetry System, the Stream Monitoring System and the Exhaust Monitoring System. The following parameters of the working environments of miners were determined: average expected concentration, average observed concentration, average expected exposure cumulation rate, average observed exposure cumulation rate, and average effective exposure cumulation rate. Mathematical formulae for determining all these indicators, acccording to the type of measurement system used in particular mines, are presented. The reliability of assessment of miners' exposure in particular measurement systems, as well as the role of the possible reference system, are discussed.

Toxicological profile for radon
Several epidemiological studies of long-term exposure to radon have reported significant increases in early mortality due to cancer and noncancer diseases. Lung cancer, respiratory diseases, kidney disease and genotoxic effects have been reported among uranium miners following long-term exposure to radon and radon daughters. An increased lung cancer mortality rate has also been reported among nonuranium hard rock miners exposed to radon in groundwater. Glossary.

Chemical contaminants in office buildings
Air quality measurements were made in 17 buildings in Quebec. Contaminants measured included airborne dust, nicotine, volatile organic compounds, formaldehyde, carbon monoxide, carbon dioxide, ozone and radon. The feasibility of using carbon dioxide as an air quality indicator of other airborne contaminants was also evaluted. Chemical contaminant levels were found to be low, but the presence of these chemicals in indoor air is of concern because of their possible synergistic effects. Airborne concentrations of dust, carbon monoxide and carbon dioxide were found to be higher than the values recommended for nonindustrial air. Carbon dioxide can be used as an air quality indicator for contaminants related to occupant activity.

Lung cancer mortality among nonsmoking uranium miners exposed to radon daughters
In a follow-up study (1950-1984) of 516 nonsmoking uranium miners, 14 deaths from lung cancer were observed compared with 1.1 expected in a reference group of nonsmoking nonminers, yielding an overall standardised mortality ratio of 12.7. Working level months (WLM) of exposure to radon daughters were estimated and it was concluded that there is a 12-fold mortality risk of lung cancer for nonsmoking uranium miners exposed to radon daughters at a median level of 296 WLM, when compared with nonsmoking nonminers. Results confirm that exposure to radon daughters in the absence of cigarette smoking is a potent cancer-causing factor that should be strictly controlled.

Mortality study among lead-zinc miners of Val Seriana (Italy)
Studio di mortalitā dei minatori di piombo-zinco della Val Seriana [in Italian]
The mortality experience of 1,392 lead-zinc-silver miners (Gorno, Northern Italy) employed during the period 1950-1980 and followed up to the end of 1986 was examined. Two separate estimates of the radon exposure level are available: 0.60 and 0.36WL (working levels) respectively. The silica exposure level was not assessed. Vital status was ascertained for 95.6% of the cohort members and their mortality was compared with expected deaths based on national rates. Significant excess mortality from oesophageal cancer, stomach cancer, lung cancer, respiratory tuberculosis, respiratory diseases and deaths from external causes was found among underground miners. Surface workers show significantly increased mortality from liver and bile duct cancer, hepatic cirrhosis, respiratory tuberculosis and respiratory diseases. Based on the 16.4 excess lung cancer cases among underground miners and their cumulative radon exposure, an attributable risk estimate ranging from 9.78 and 16.31 cases per million person-years and WLM (Working Level Month) was calculated.
