| Abstract:: |
| Objective To establish a method for estimating internal dose from aerosol inhalation in non-uranium miners.Methods Aerosol samples in a tunnel in Dongchuan Copper Mine in Yunnan Province were collected by portable high flux air sampler. Radionuclides collected at the sampler filters were analyzed by the gamma spectrometry. Annual committed effective dose due to inhalation of the aerosol dust was estimated using the formula provided by ASTM.Results Radionuclides collected in two aerosol samples were anlayzed, the annual committed effective doses due to inhalation of 1 μm and 5 μm aerosol were estimated.Conclusion The method of using high flux air sampling and gamma spectrometry is explored to estimate the dose from aerosol inhalation. |
