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 one in every hundred cancer deaths could be attributed to workplace radiation exposure.
"The findings are important not only for the protection of workers in the nuclear industry but also for medical staff and the general population," since the level of doses received by nuclear workers is comparable with that received by patients repeatedly exposed to CT scans or other radiology procedures, said IARC researcher Dr Isabelle Thierry-Chef.
"This stresses the importance of striking a balance between the risks and the benefits of such medical imaging procedures," she added.
The average age of workers in the study was 58 years.
