At its height, it was putting more than 200,000 times the normal amount of radioactivity into the area due to poor waste disposal practices. WebSome species of radioactivity occur naturally on Earth. A few species have half-lives comparable to the age of the elements (about 6 × 109 years), so that they have not decayed away after their formation in stars. Notable among these are uranium-238, uranium-235, and thorium-232. Also, there is potassium-40, the chief source of irradiation of the body …
