Abstract

it is to seek in the implementation details about the management of the naturally occurring radioactive materials. Especially for natural radioactivity concentration in raw materials and tailings and its mineral products are used for manufacturing refractory products.It needs to be further improved．The classification method is based on the γ radiation dose rate limit under the measured environment or material surface at different heights and the activity concentration of radionuclide.The aim of this work is to investigate the Control index problems the different influencing factors or parameters of radiation level.The results show that the limits of Radionuclide on the different of the Influence factors with the height of the raw radioactive materials and its Tailings or its product.It is mainly studied from three aspects: ①the judgment of the raw radioactive materials and its Tailings or its product.②the building materials form of the raw radioactive materials and its Tailings or its product were judged.③The absorbed dose rate(Iγ) and radium equivalent activity(Raeq)，alpha index (Iα) , et al. wered assessed.The Results show that the control index about the representative management．It will play an important role in radiation protection and measurements，and it provides technical basis for future evaluation standard of scientific and practical management.
