In summary, after the nuclear bombing of Hiroshima, people still live there and the most dangerous isotope, Iodine 131, has a half-life of 8 days, so after a couple of months it is essentially gone. Ceasium 137, with a half-life of 30 years, is also produced but is not easily absorbed in the body. The initial casualties were mostly due to the blast and immediate effects, with only a small percentage attributed to radiation.

Straight away, radiation is really the least of your problems if somebody detonates a bomb above your head.
Only about 10-15% of the initial casualties were due to radiation and long term very few - something like a few hundred excess cancer deaths over the last 50years.

Basically everybody close enough to receive a dangerous radiation dose are killed by the blast or it's immediate results.

That is a legitimate question.

The most dangerous isotope from a Hiroshima type bomb is probably Iodine 131 with a half life of 8days, so after a couple of months it is essentially zero.
Ceasium 137 with a half life of 30years is also produced but it's not very easily absorbed in the body.
