What was the pollutant in chernobyl air?

Answer 1

Nuclear fallout, from the explosion at the power plant, would be the major one. You'd probably find the same pollution you would find in most other places, too, though.

Answer 2

The pollutant released into the air during the Chernobyl disaster was primarily radioactive isotopes, such as iodine-131, cesium-137, and strontium-90. These isotopes are harmful to human health and the environment due to their radioactivity.
