Waves or particles from the nucleus of unstable radioactive atoms emitted determined to become stable? Mainly two types of radiation, ionizing radiation and nonionizing radiation. Ionizing radiation of alpha, beta particules, neutrons, X rays and gamma rays. Ionizing radiation, which ionization chambers, Geiger-Mueller detectors, scintillation counters, fluorescent counter can be measured, etc., are harmful to human health in the levels of molecules, cells, tissues, organs and systems. These side effects may also be referred to somatic and genetic. One problem arises? Acute radiation sickness syndrome? three subgroups syndrome called hematopoietic syndrome, gastrointestinal syndrome, and neurovascular disease. Exposure time, distance and armorisation are the main elements of protection against radiation...
