Chernobyl had tonnes of radioactive material, a nuclear bomb has much less material, in the kilograms. After Chernobyl blew its lid off, the reactor core was laid open. Witnesses said they could see a beam of light going into the sky. It was the radiation ionizing the air. A helicopter that was trying to drop sand onto the reactor accidently flew too close over it, giving the pilot a lethal dose.
