How long after Hiroshima was it safe?

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.

Does it rain after a nuclear explosion?

Radioactive fallout is rarely a good thing. But new research suggests charged particles emitted from Cold War–era nuclear tests may have boosted rainfall thousands of kilometers away from the testing sites, by triggering electrical charges in the air that caused water droplets to coalesce.
