摘要
Abstract
The dose rate constant,radial dose function,one-dimensional anisotropy function and two-dimensional anisotropy function of domestic 6711 particle source were simulated by MCNP software.The error between the dose rate constant and the recommended value reported by TG 43-U1 was-0.83％.The radial dose function in the range of 0.05-10 cm was obtained,and the fifth-order polynomial fitting of the data in the range of 0.25-10 cm was proposed to improve the accuracy of the fitting function.The one-dimensional anisotropy function and the two-dimensional anisotropy function in the range of 0.25-7 cm are obtained,and compared with the relevant literature,it can be seen that the difference of the structure of the domestic type 6711 particle core will cause the phenomenon of the one-dimensional anisotropy function and the two-dimensional anisotropy function.关键词
