> Decades later, just in our block, there have been many cases of cancer (1 renal carcinoma -- my mom, 1 testicular cancer, 1 melanoma, 3x breast cancer). Sometimes I wonder if that's the natural incidence or if it is in fact a cancer cluster caused by remnants of Cobalt-60. That is such an interesting and scary thing about it. It is really hard, and takes a lot of careful data collection, to figure out how much cancer is "normal" everyday cancer from smoking, genetics, voodoo curses; and how much is actually "extra" cancer from possible radiation exposure. It would be especially difficult on something as small scale as a neighborhood block, since random variation of even one or two extra or fewer people unlucky enough to get “natural” cancer could completely skew an analysis attempt.
