All these things are pretty horrible, especially what they did to Junko Furuta. Something nobody else has mentioned though is acute radiation poisoning (such as experienced by survivors of the Hiroshima and Nagasaki atomic bombs, as well as the firefighters who first responded to the Chernobyl disaster). Anything over 5000 rads will cause extreme nervousness and confusion; severe nausea, vomiting, and watery diarrhea; loss of consciousness; and burning sensations of the skin - which occurs within minutes of exposure and lasts for minutes to hours. Then you get a latent stage that lasts for a few hours or less where the symptoms disappear, but then you get a return of watery diarrhea, convulsions, and coma. Death occurs within 3 days of exposure. Death is due to collapse of the circulatory system as well as increased pressure in the confining cranial vault as the result of increased fluid content caused by edema, vasculitis (destruction of vessels and arteries by inflamation), and meningitis. There's absolutely nothing you can do but die horribly as your body shuts down - all the medical staff can do is try and make you as comfortable as possible until the end. The worst part is the latent stage where there's a short period where you think you're okay and will pull through - only to come crashing back to reality in the worst way.
