The intrinsic efficiency is defined as the ratio of light energy emitted during heating to energy absorbed during gamma irradiation. This factor was measured for four commonly used thermoluminescent phosphors to give the following results LiFTLD-100, 0.039 Li2B4O7Mn, 0.073 both corrected for supralinearity CaF2Mn, 0.44 and CaSO4Mn, 1.2. The method of measurement involved calibrating a detector, which consisted of a narrow bandpass filter in conjunction with a photomultiplier, by means of the light of a standard lamp diffusely reflected from a MgO button having the same size, shape, and position as the phosphor-bearing planchet. A correction was made to account for the fact that the phosphor samples were not Lambertaian sources. Author
