Yeah, there's the 20 year cancer. There's also been a contained accident in a nuclear plant in Japan in the past ten or twenty years where no radiation was released to the public, but the 3 first responding workers vomited green...vomit...had all their hair fall out, and died the third day after the accident. I remember that one on the news. You'd have to torture my family to make me go anywhere near a melted down power plant.
I don't think that reverance or respect for the dead needs the dead to be hidden from sight completely. It is the attitude that you bring, as a witness to a dead body, that matters, not the display and witnessing of a dead body, per se.
