I stuck on a documentary about Chernobyl, there was a clip of a pair of boots the fireman were wearing near the plant and the levels of radiation went stupidly high. How can an object like the boots show such a high reading but other objects in the room show lower readings? They also shown a cloth the nurses used on the fireman and the reader did the same thing.
Howcome that happens? Does radiation “stick” to objects?
In: Physics
Radioactivity comes from radioactive isotopes, such as cesium-137 (half-life 30 years). If these stick to porous materials such as leather or cloth, it may be hard to wash them off. And probably not worth the trouble.
