My father, who found himself with both thyroid and prostate (both of which he’s already recovered from) in the span of some months, has long been planning on visiting me, but has been prevented from coming by multiple check-ups requiring pre- and post-op prepwork. He’s finally coming this Friday, after doing the first scan of its type mid-week for his prostate. Calls me up today he does, and tells me the doc told him to maintain a distance of 2-3 feet from everyone for like a week. Why?? Turns out he’s radioactive!! A regular isotope!
