Calculation of internal exposure dose coefficients for Chinese adult reference phantom
摘要
Abstract
In the fields of nuclear science and technology,nuclear energy and nuclear medicine,accurate assessment of internal exposure dose received by relevant public,professionals,and patients is an important guarantee for personnel health and safety during work,nuclear accidents,and radiation therapy.Referencing the ICRP biokinetic model and radionuclide information,the internal dose coefficient is obtained by calculating the Specific Absorbed Fraction(SAF).The correctness of the calculation method is verified using the ICRP reference human phantom.Finally,based on Chinese adult reference human phantom,a database of internal radiation dose coefficients for Chinese adult reference human is calculated.The database obtained includes the Specific Absorbed Fraction(SAF)of α,β,and γ rays for Chinese adult reference human,the committed equivalent dose coefficients for sensitive organs(tissues)of Chinese adult reference human,and the committed effective dose coefficients for Chinese adult reference human.The calculated results were compared and analyzed with the internal dose conversion coefficients provided by GB 18871-2002.It was found that using the internal radiation dose conversion coefficient database of Chinese adult reference human can more accurately assess the internal dose caused by the intake of radioactive nuclides by Chinese adults.关键词
