Chernobyl is not comparable to a nuclear bomb. Chernobyl is a reactor, made to release a steadily amount of radiations for years to make electricity.
Chernobyl irradiated a large area because the graphite that was located in the reactor core has burned, and the fumes have been carried by the wind, taking a lot of high-level activity nuclear waste hundred or thousands of kilometers away.

A few days after a bomb explodes, most of the radiations would have depleted.
