In Japan, it was discovered (I don't recall how) that an apartment complex had been built using steel recycled from the atomic blast area. (Probably from the Mitsubishi Steel Works in Nagasaki, though I don't recall for sure.)
Radiation levels were checked, and found to be well above what was considered safe at the time (which is probably more than is allowed now). Everyone was relocated and the buildings demolished and the steel beams were disposed of properly.
Health records were checked, since the apartments had been occupied for several decades. It was found that the incidence of cancers of all types was significantly different than the normal population.
It was significantly
lower.
Oddly enough, a study done of survivors of both atomic bombs found the same thing - a significantly lower cancer rate compared to the unexposed population.
This is cited as an example of the
hormetic effect, which is well documented, but not well understood.
