PARIS – Prolonged exposure to even low doses of radiation increases the risk of cancer, according to a new study of workers in the nuclear sector in Britain, France and the United States.
The results, published Wednesday in the British Medical Journal, provides “direct evidence about cancer risks after protracted exposures to low-dose ionizing radiation,” said the International Agency for Research on Cancer (IARC), the cancer agency of the World Health Organization, which coordinated the study.
The findings demonstrate “a significant association between increasing radiation dose and risk of all solid cancers,” said the study’s co-author, IARC researcher Dr. Ausrele Kesminiene.
“No matter whether people are exposed to protracted low doses or to high and acute doses, the observed association between dose and solid cancer risk is similar per unit of radiation dose,” he added.
The International Nuclear Workers Study (INWORKS), a collaboration between international partners, evaluated the exposures of more than 300,000 nuclear workers in Britain, France and the United States between 1943 and 2005.
The results showed that the risk of death from solid cancers was “modest” but that 1 in every 100 cancer deaths could be attributed to workplace radiation exposure.
