The use of radiation or ionizing radiation is increasingly expanding. Research and application of radioactivity has made many advances, upsetting techniques in industry, agriculture, medicine or biology. The achievement of nuclear physics allows the use of nuclear energy in many national economic sectors. Later, it is certain that the huge energy needed for human activity will be largely nuclear power, through nuclear power plants. In our country today, radioactivity has also been widely used in many sectors: mines, geology, oil and gas exploration, health, etc. ... In the health sector alone, the team of radiologists must continue contact with X-rays, was also very crowded. Although there are facilities to protect and protect individuals, the risk of infection is not small. The benefits of radiation are great, but the harm is not small. Radioactive diseases also had obvious manifestations of victims of Japanese cities Hiroxima and Nagaxaki (Hiroshima and Nagasaki), after the atomic bomb explosion. Occupational radiation infection has also appeared in people who are exposed to radiation. Since 1986, skin inflammation has been observed in patients undergoing radiography and electro-optic physicians. It was Marie Curie, the female scientist herself, who suffered injuries in her hands because while working, she used hand-held radioactive radio pieces. The Ministry of Health - Invalids and Social Affairs and the Vietnam General Trade Union have issued a circular specifying a number of occupational diseases and regimes for remuneration for state employees and workers suffering from occupational diseases, including infectious diseases X-rays and radiation, with pathological and skin manifestations, in bones and lungs. So far, there have been a few cases of X-ray infections seen in electro-physicians who have been assessed for occupational diseases. The main manifestations of blood, with leukocyte images in the circulating blood, persist after many years, despite cessation of X-rays, and after many nursing treatments. Through a series of surveys of people exposed to radiation either during manipulation or during exploration ... there were also blood manifestations. In some cases, there are variations in chromosomes.
