Abstract
Abstract Dosimetric materials used in practice generally exist in the form of powder or chips which are unsuitable for conventional optical absorption spectroscopy (OAS) measurements. Photoacoustic spectroscopy (PAS) gives information about absorption properties of opaque and powdered samples in a wide range of optical absorbance. Photoacoustic spectra of differently doped LiF samples (LiF:Cu,Mg,P from Beijing, LiF doped with Ti and different amounts of Mg, and TLD-100) were recorded at various high (>100 kGy) 60Co gamma doses in the 220-600 nm wavelength region. PA and OA spectra were compared and similarities as well as differences were found. Dependence of spectra on the Mg content and on the irradiation dose is discussed. Evaluation of the PA spectrum of LiF:Mg,Cu,P revealed no extra peaks compared with LiF:Mg,Ti.
