Abstract
SEVERAL authors1–3 have studied how the intensity of an X-ray beam, E, affects the parameter “a” which defines the rate of generation of the late stage anion vacancies. Mitchell et al.1 have shown that a ∝ E2. Abramson and Caspari2, however, have suggested that for large values of E, a should vary linearly with E and for low intensities a should vary as E2. According to Pooley3, the power x of E in the relation a ∝ Ex should be unity for large values of E and should increase to a limiting value of 1.5 on decreasing E. We have made investigations with very pure KCl crystals using the thermoluminescence technique4 to find the variation of x in the relation a ∝ Ex for low and high X-ray intensities.
