OK, I will.
Q. Is there still radiation in Hiroshima and Nagasaki?
Answer: "Atomic bombs differ from conventional bombs in emitting explosive energy on an entirely different order of magnitude and radiation. Of the emitted energy, 5% was initial radiation and 10% was residual radiation."
"The initial radiation emitted at the moment of detonation inflicted great damage to human bodies. Most of those exposed to direct radiation within a one-kilometer radius died. Residual radiation was emitted later. Roughly 80% of all residual radiation was emitted within 24 hours. Research has indicated that 24 hours after the bombing the quantity of residual radiation a person would receive at the hypocenter would be 1/1000th of the quantity received immediately following the explosion. A week later, it would be 1/1,000,000th. Thus, residual radiation declined rapidly."
The radiation in Hiroshima and Nagasaki today is on a par with the extremely low levels of background radiation (natural radioactivity) present anywhere on Earth. It has no effect on human bodies."

I reckon that this site is about as well read on the subject as one can get!
This wasn't my question, but thanks for the info.
