In order to understand radiation protection level of the interventional diagnosis and treatment room of a Xinjiang hospital, determine whether the shielding effect meets the requirements of national standards. According to the maximum running parameters about the facility and some other related parameters of the interventional room, the article uses estimation theory to calculate and analyze shielding effect of the interventional diagnosis and treatment room. The results show that design thicknesses of surrounding walls with the exception of the floor are greater than the theoretical calculation ones, which has indicated that the shielding effect(except the floor) meets the requirements of national standards. The floor slab should be increased at least 0.94 mm thickness lead-equivalent to meet shielding requirements. ©, 2015, Atomic Energy Press. All right reserved. Source

The latest decay scheme, through theoretical modeling, the establishment of soil uranium series, thorium series, nuclides 40K γ radiation and the environment caused by the surface air absorbed dose rate relationship, and compared with the Beck formula to further verify the accuracy of the derived formula. Ground for future environmental γ radiation dose rate is calculated to provide the formula reference. Source

Analogy is a inference method, according some properties of a class of things to inferring the similar things should also have the similar properties. The analogy of same radionuclides is widely used in radioisotope logging environment impact assessment so far. This paper is to provide fFor future providing a theoretical calculation method and analogy method between different radionuclides in radioisotope logging environment impact assessment. In this paper, using the latest decay scheme, through theoretical modeling, the aim is the the establishment of 131Ba and 131I radioisotopes gamma radiation dose rate calculation method, and try to carry out analogy research on gamma radiation dose rate of different radioisotopes with the same activity. The results show that the analogy of different radionuclides is feasible, which provides the new method reference for carrying out such radiation environmental impact assessment in future. Source

The coal was divided into exempted supervision, unrestricted exploitation, restricted exploitation and prohibited exploitation for coal mine supervision in Xinjiang. And based on the above meationed, the limits of radionuclides concentration and gamma radiation dose rates of coal were studied. They could determine the reasonable classification technical index system for coal mine associated with radionuclides. And they could also offer the technical basis in formulating scientific and practical classification technical standard of coal mine associated with radionuclides in Xinjiang. Source
