Abstract: Neste artigo apresentamos as bases da Física das radiações, as fontes naturais e artificiais, os efeitos biológicos, a proteção radiológica. Examinamos também a sequência de eventos que resultou no acidente de Goiânia com uma fonte de césio-137 de um equipamento de radioterapia abandonado e suas terríveis consequências.

“…There are several types of ionizing radiation and each has different penetration power, causing different degrees of ionization in matter. 14,15 Ionizing radiation penetrates according to its type and energy. While alpha particles can be blocked by a sheet of paper, beta particles require a few millimeters of a material such as aluminum, to block them, while high-energy gamma radiation requires dense materials to block it, such as lead or concrete.…”

“…While alpha particles can be blocked by a sheet of paper, beta particles require a few millimeters of a material such as aluminum, to block them, while high-energy gamma radiation requires dense materials to block it, such as lead or concrete. 14,15 Ionizing radiation can occur naturally, for example, by the decomposition of natural radioactive substances such as radon gas. The rate at which a radionuclide decomposes (becomes less radioactive) is called half-life, which is the time it takes for a radioactive material to reduce its activity by half.…”
