| Objective To establish a way to measure intake of radionuclides and estimation of committed effective dose based on gamma spectrometry analysis. Methods Using gamma spectrometry to measure radionuclides excretion feces and urine of internally contaminated persons. The measured values are to be used to estimate the in take of radionuclides and committed effective dose. The calculation process was performed by a computer code. Result This method can be used to estimate internal contamination and the coputer code may provide quick and exact results. Conclusion This research provides a rapid method to measur and estimate radionuclides causing internal contamination, and it may meet the needs in emergency cases. |
