This is no news: chronic exposure to ionizing radiation, particularly among professionals in the nuclear industry, increases the risk of cancer. But the assessment of this risk could have been underestimated, according to a study published in the British Medical Journal and conducted by an international team, including French people attached to the Institute of Radiation Protection and Nuclear Safety (IRSN).

It emerged that, for each unit of radiation (measured in grays, Gy) absorbed by workers, the risk of death from cancer increased by 52%. “In principle, no professional is exposed to radiation doses of 1 Gy, even cumulative, because the regulatory exposure rate does not…
