1.
(1) As a tracer atom
The chemical and biological properties of the radioisotopes and their compounds used in isotope tracing are the same as the corresponding common elements and their compounds in nature, but they have different nuclear physical properties
Examples of the application of Table 18-6 in the test
(2) Use its rays
Many radioactive isotopes are very harmful to the human body, but their radiation properties can be used to serve humans
2.
The radiation dose of X-rays and γ-rays in the internal and external environments of radioisotope laboratories should meet the limit requirements of exposure dose to the public specified in the "Basic Standards for Ionizing Radiation Protection and Radiation Source Safety" (GB18871-2002); β surface pollution level should be Meet the requirements in Appendix B of "Ionizing Radiation Protection and Radiation Source Safety Basic Standards" (GB18871-2002) that the β surface pollution in the supervision area is less than 4Bq/cm²
