WebIt is important to regulate the exposure of humans to radiation. The amount of radiation received by a person is called the dose and is measured in sieverts (Sv) One sievert is a very big dose of radiation. It would cause acute radiation poisoning. People would normally receive about 3 mSv (0.003 Sv) in one year. WebDetection of beta radiation is very specific because beta particles are more penetrating than alpha particles. On the other hand, ... For alpha and beta particles to be detected by ionization chambers, they must be given a thin window. This “end-window” must be thin enough for the alpha and beta particles to penetrate.
