Abstract:

A LiF dosimeter has been developed to measure gamma-ray exposures between 100,000 and 2 x 10 to the 9th power R. Applicability of the LiF as a megarad dosimeter depends on the fact that a thermoluminescent glow peak at a temperature about 450C has a negligible response to radiation below exposures of 100,000 R. A number of crystal specimens were examined and most of them were found to have the high temperature glow peak which could be followed as a function of exposure for three to five decades. Similar responses of the high temperature glow peak were found for the dosimeter when exposed to 2-MeV pulsed electrons or thermal neutrons. Author
