Hi - we as mods have approved this thread, because while this is a homework question, it is asking for clarification or resources, rather than the answer itself, which is fine according to our rules. This policy is further explained in this Rules Roundtable thread and this META Thread.

As a result, we'd also like to remind potential answerers to follow our rules on homework - please make sure that your answers focus appropriately on clarifications and detailing the resources that OP could be using.

Additionally, while users may be able to help you out with specifics relating to your question, we also have plenty of information on /r/AskHistorians on how to find and understand good sources in general. For instance, please check out our six-part series, "Finding and Understanding Sources", which has a wealth of information that may be useful for finding and understanding information for your essay.

Atomic Accidents by James Mahaffey has a chapter on them. It's only a chapter, but it goes into the scientific details of what happened to their bodies without getting too complex for a layman reader. The book overall is wonderful and I highly recommend reading the whole thing. It's free to read on Kindle Unlimited if you have Prime. I also recommend his first book, Atomic Awakening, for a general history of nuclear power.
