I can't find a field for things I want to study?

I really enjoy psychology, but have been quite interested in nuclear engineering lately. I would love to find a field that combines them? I've heard of things like radiation oncology research, but more precisely I'd like to study the psychological effects of radiation. Chernobyl is a big interest of mine, and I want to know how it affected (and still continues to affect) the people around the area. Not only that, but I would like to pursue nuclear engineering, however math is not exactly my strong suit and I know that essentially means i'm not cut out for that field. Any advice??
