Thermal diffusivity, specific heat, and thermal conductivity of A-150 plastic (tissue-equivalent)

Abstract

Some thermal properties of A-150 tissue-equivalent plastic have been determined. The results are: thermal diffusivity, 2.72*10^-3 cm² s^-1+or-0.4%; specific heat, 1.72 J g^-1 K^-1+or-1.3%; and thermal conductivity, 5.3*10^-3 W K^-1 cm^-1+or-1.4%. The significance of the measurements for the design of a calorimeter core calibration heater is briefly described.
