Radiation is divided into electromagnetic radiation and nuclear radiation. Nuclear radiation hazards, such as cobalt-60, cesium-137, iridium-192 sources such as γ-rays; kr-85 sources such as β-rays; 241Am-Be source, 24Na-Be source, 124Sb-Be source and the energy of more than 10M of the electron gas pedal neutron rays; non-sealed sources of β-, α-rays; a variety of industrial, medical X-ray equipment produced by χ-rays and so on. radiation produced by various industrial and medical X-ray equipment, etc. With the large number of applications of nuclear energy and nuclear technology in industrial and agricultural production, health care, scientific research and national defense, more and more people are irradiated, the harm of radiation can not be ignored.
Long-term exposure to radiation will make the human body feel uncomfortable, and in severe cases, it can cause damage to human organs and systems, leading to the occurrence of a variety of diseases, such as: leukemia, aplastic anemia, a variety of tumors, ocular fundus pathology, reproductive diseases, premature aging, etc.
