researchers looked at a group of nuclear workers to see if being
exposed to low doses of ionizing radiation in the workplace may
or may not be linked with fatal leukemia (death caused from
leukemia). Why was this study done? Previous studies suggest
exposure to high doses of ionizing radiation may cause leukemia.
However, it is still uncertain if low doses of ionizing
radiation, which are common in some workplaces, m
