Is Chernobyl radiation free already?

The Chernobyl reactor is still very radioactive. Specifically, the reactor is about half as radioactive as after the accident, because Cesium137 has a half life of 30 years. read more

No. The Chernobyl reactor is still very radioactive. Specifically, the reactor is about half as radioactive as after the accident, because Cesium137 has a half life of 30 years. If you were exposed to certain parts of it you could get a fatal dose of radiation in minutes. It will take hundreds of years for the area to be safe again. read more

Levels of radiation at Chernobyl Immediately after the explosion The radiation levels in the worst-hit areas of the reactor building, including the control room, have been estimated at 300Sv/hr, (300,000mSv/hr) providing a fatal dose in just over a minute. read more

Chernobyl was the worst case scenario. The biggest contributor to the spread of radioactive fallout from Chernobyl was the total absence of a containment building. After that comes the fire in and around the exposed melted down core. The smoke of the fire was carried high in the atmosphere by the heat. read more

Chernobyl radiation radius was outlined in the 30 km. Because it was assumed that if there was a nuclear explosion, the so-called second zone would have been just 30 km (the first zone – the continuous destruction – is a 10 km). read more
