||This case-control study examines potential associations between telephone linework and the occurrence of leukaemia with the exception of chronic lymphocytic leukaemia. Workers with lifetime exposure scores to extremely low frequency non-ionizing radiation above the median for the population show an excess of leukaemia 2.5 times higher than workers below the median (95% confidence interval (CI) 0.7-8.6). Those individuals with a long duration of employment in jobs with intermittent peak exposures may be at a higher risk of leukaemia than those with a constant exposure level. Analyses that allow for a latent period suggest that the risk is associated with exposures that occurred 10 or more years before death. Workers with peak exposure scores to extremely low frequency non-ionizing radiation above the median have odds ratios of 2.4 (95% CI 0.7-9.0) and 6.6 (95% CI 0.7-58) for latent periods of 10 and 15 years, respectively. The data suggest an increasing risk with increasing exposure (p for trend = 0.05) when cumulated scores are based on peak exposure scores. The numbers in this study are small and the differences observed may be due to chance.
