Abstract |
Radon (Rn) and thoron (220Rn) daughter exposure data collected over a 10 year period show that the distribution of the effective dose equivalent (EDE) for all Norwegian miners complies generally with the ICRP recommendations. 23% of the miners working in 2 of the mines surveyed receive about 70% of the collective EDE. Thoron daughter exposure represents <10% of the EDE. Factors affecting radon and thoron daughter concentrations in mine atmospheres are: temperature and atmospheric pressure changes, type of mining operation and levels of dust and diesel exhaust fumes. |
