In movies, during nuclear fallout, people in hazmat suits are usually seen being sprayed down by a liquid (seemingly to control the radiation) but if Radiation can penetrate clothes and metal then how can this liquid be used to control the spread of Radiation?
In: Chemistry
It’s soapy water.
The point of the suits is to help prevent you from inhaling or ingesting contaminated particles. Certain kinds of ionizing radiation (alpha and beta particles) are far more dangerous when they are inside your body. So after leaving a contaminated area the suits are hosed down with hot soapy water to wash off any dust or other particles that may have stuck to them.
