Abstract
LiF type 7, in loose powder form, has been irradiated with X-rays generated at potentials between 50 and 25 kV, having effective energies between 26 and 11 keV, and also with 60Co gamma -rays. The response of the LiF, per rad in LiF, was not significantly different for the X-rays and the 60Co radiation. X-ray doses in the LiF were calculated from measurements made with a free air chamber.
