An Exposure-Time-Response Model for Lung Cancer Mortality in Uranium Miners

This article is about uranium miners and radon progeny (airborne radiation), not asbestos. The authors studied 3,366 white men in Arizona, Colorado, New Mexico and Utah who had been given a medical examination and had mined uranium underground for at least one month. They built an exposure-time-response model to estimate lung cancer deaths from cumulative radiation exposure, measured in working level months. They then tested whether excess risk followed an absolute or a relative risk pattern, with median latent periods of 5, 10 or 15 years. The absolute risk hypothesis predicted far too many deaths among miners under 45. The model using relative risk and a 10-year median latent period gave the best overall fit. The authors concluded it was a good predictor of when the lung cancer deaths occurred. Non-smokers had much lower radiation-related lung cancer than smokers. Light and heavy smokers had about the same level. The authors noted that the expected rates they used may have been too high, and that longer follow-up is needed to test the shape of the model.
