Abstract

The relative energy response of 0.4- and 1.16-mm thick LiF TLD-100 showed decreases of 5 and 9%, respectively, for 22-MV x rays and 6-, 9-, 12-, 15-, and 18-MeV electron energies when compared to responses for /sup 60/Co ..gamma.. rays in polystyrene and water media. The theories of Burlin, Burlin et al., Almond and McCray, and Holt et al. do not agree with these findings. Reasonable agreement is obtained with the Fregene expression and with Almond and McCray and Holt et al. only when the photon energy response at /sup 60/Co is calculated from the Fregene expression. The hitherto conflicting results are resolved where sufficient experimental and theoretical details are given in light of the present findings.
