Nuclear Workers Face Higher Mesothelioma Risk
Pleural mesothelioma is most often associated with asbestos exposure, but a new study suggests that nuclear workers may also be at higher risk for the cancer because of long-term, low-level radiation. A new National Institute for Occupational Safety and Health (NIOSH) study pooled a group of 119,195 US nuclear workers. The workers were employed at one of four Department of Energy nuclear weapons facilities or at the Portsmouth Naval Shipyard. They were followed from the start of their radiation work, between 1944 and 1952, though 2005. Their risk of death from mesothelioma and other cancers was then compared to that of the general population. “For most outcomes, mortality was below expectation compared to the general population, but mesothelioma and pleural…
