Abstract:
Objective To investigate the radiation pollution level of radon and ? radiation in air in different type of buildings. Methods 22 different type of rooms were selected and common measuring methods and REM-2 Radon exhalation rate apparatus and FD-125 Rn-Th measuring instrument were used. Results It indicated that the indoor radioactive contamination mostly root in the exhalation of soil and building material, secondly outdoor radon and ? radiation, water and the wall contributed little. Conclusion The results of the present paper have laid a foundation for the further study on the effect of radiation on human health and the protective technique.
