Science Papers Is the radon risk overestimated? Neglected doses in the estimation of the risk of lung cancer in uranium underground miners. 2002, by Philippe Duport, Ph.D., International Centre for Low Dose Radiation Research, Institute of the Environment, University of Ottawa, Ottawa, Canada. pduport@uottawa.ca Only the exposure to inhaled radon decay products is usually taken into account in the determination of the risk of radiogenic lung cancer in uranium miners. However, the elevated lung cancer risk in uranium miners is due to the total dose of radiation received by that organ, not to the dose from inhaled Radon-222 decay products (222Rn D.P.) alone. Lung doses from sources other than 222Rn D.P. may reach 25% to 75% of total effective dose, absorbed dose or equivalent lung dose, are correlated to 222Rn D.P. doses and are quite variable between facilities. Therefore, to neglect these doses leads to a systematic overestimation of the risk of lung cancer |
