Lithium fluoride (activated) crystals were prepared by the Bridgeman-Stockbarger and Czochralski methods. Measurements have been made on the scintillation response of a LiF crystal to photon energies between 8 and 1333 keV. The tissue dose in rads was calculated and compared to the response of the LiF crystal over the same energy range. The response of a single titanium-activated LiF crystal was compared to the response of a NE 109 air-equivalent scintillator at 60Co energies. The absorption and emission spectra of the LiF crystal were obtained.
