Identify the radiation!! Smoke detectors are safe because the plastic case easily stops the _______ radiation that is used. ________ is dangerous because it easily penterates skin but is stopped (absorbed) by the body. Nuclear power stations are built in thick concrete to block _______ radiation. The thickness of card can be measured using ______ radiation because some is absorbed but some passes through. ________ radiation can be used to see inside metal parts as it is able to penetrate, similar to x-rays ALPHA BETA GAMMA BETA GAMMA
