摘要
Abstract
Objective To estimate the neutron dose using 24 Na energy spectrum analysis method. Methods Genius-2000 GeomComposer software package was used to calibrate the efficiency of the detector. Results The detection efficiency of the detector toward y photon with an energy of 1. 368 MeV was quickly found to be 4.05271 × 10-2 while the error of the software was 4.0%. The estimated dose value of the neutron irradiation samples was between 1. 94 Gy and 2. 82 Gy, with an arithmetic mean value of 2. 38 Gy. The uncertainty of the dosimetry was about 20. 07% . Conclusion The application of efficiency calibration without a radioactive source to the energy spectrum analysis of the 24 Na contained in human blood will accelerate the estimation process.关键词
