radioactive contamination

Marie Curie died of aplastic anemia, a disease brought on, in her case, by exposure to a large amount of radiation from both her laboratory work and from her work running field x-ray machines during the First World War. There was no surprise there, given the little known about radiation and its effects on our bodies when she did her early work. But it turns out that it’s not only Marie and Pierre Curie who were contaminated - even her notebooks are stored in a lead box.
