Ian Fairlie – Radiation and Cancer: Risks of Leukemia in Nuclear Workers More Than Double Previous Estimate

In 2013, I discussed several epidemiological studies providing good evidence of radiogenic risks at very low exposure levels.

A powerful new study has been published in Lancet Haematology [1] which adds to this evidence. However the study’s findings are more important than the previous studies, for several reasons.

First, it provides “strong evidence”, as stated by the authors, of a “dose-response relationship between cumulative, external, chronic, low-dose, exposures to radiation and leukaemia”.

Second, it finds radiogenic risks of leukemia among nuclear workers to be more than double the risk found in a previous similar study in 2005. The excess relative risk of leukaemia mortality (excluding workers exposed to neutrons) was 4.19 per Gy.
