Self-shielding factors of LiFTLD are important parameters when the TLDs are used for dosimetry meas-urements of n-γ mixed field.MCNP simulations of the self-shielding factors were carried out for LiFTLDs of different sizes
densities and 6Li contents.And the calculated results were compared with those based on a theoretic formula and Horowitz’s method.Meanwhile
an experiment was designed to verify their dosimetry accuracy.The model and method adopted in MCNP were proved to be reliable.LiFTLDs available at CAEP
of different sizes
shapes and materials
and self-shielding factors of which were not available in the literatures
were simulated based on a reasonable model using MCNP in this paper.The results are of significance for measurements of n-γ mixed field and for studies on the LET effects of TLD.
