1, radioactive isotopes and radiation devices must be set up in the use of protective facilities. Its entrance must be set up radioactive signs and the necessary protection of safety interlocks, alarm devices or work signals.
2, the unit must set up a person to manage radioactive sources and radiation devices, regular inspection, maintenance and make written records. Radioactive sources and instruments, equipment failure, should be handled by a person.
3, radioactive isotopes and ray devices must be used in strict accordance with the safety regulations for operation, strict control of the irradiation dose, to prevent harm to the human body, to avoid the occurrence of radiation accidents.
4, radioactivity isotopes and radioactive sources of the use of units must set up a special source library, strict management, to prevent leakage, loss. Establishment of a sound storage, receipt, return registration system; equipped with the necessary protection detection instrumentation and protective equipment; the establishment of emergency response program.
Application of radioactive rays
1, ray detection. Gamma rays through the sample, if the sample has a trachoma or crack, then the ray in the absorption of the place is reduced, so in the sample behind the photographic negative, after the development of the negative will leave the corresponding traces.
2, in the medical application. Radioactive rays can make the cancerous tissues damaged, inhibit the development of cancer, use it can also disinfect and sterilize, the human body internal perspective, and so on.
3, in the application of agriculture. Seeds after appropriate irradiation of rays, can stimulate growth and development, so that crops mature earlier, increase yields and cultivate new varieties. China has carried out the promotion of rare earth agricultural technology, and obtained good economic benefits.
