“…The agreement with the Burlin expression using β 2 was also obtained for 7 LiF dosimeters encased in different materials and exposed to 137 Cs, 54 Mn and 60 Co gamma-ray sources (Simons and Emmons 1979). For the same type of dosimeter ( 7 LiF) Olivera et al (1994) found a very good agreement between experimental results and the Burlin expression for irradiations with x-rays for effective energies between 19 keV and about 180 keV.…”

Several types of thermoluminescent dosimeters (LiF:Mg, Ti, Al2O3:Mg,Y and CaF2:Mn) were irradiated at different depths in a water phantom placed at a distance of 2.5 m from a panoramic 60Co source. Detectors were encapsulated in Plexiglas holders with a wall thickness of 0.5 cm. Reference dosimetry was carried out using a Fricke dosimeter and an ionization chamber. The experimental data were compared with the predictions of the general cavity theory for gamma ray spectra at different depths of water. The suitability of parameters of the cavity theory proposed by different authors was evaluated in the analysis of the experimental results. The results show that there is no need for any modification to the original and simple Burlin expression which gives very good agreement with the experimental values.

“…For agammaray source, the energy absorbed is a function of the mass-energy absorption coefficient in either case. Hence, the energy absorbed in the TLD per unit mass can be related to the energy absorbed per unit mass in the surrounding medium, by the ratio of the mass energy absorption Spectrum calculations (7). included both Compton and pair production interactions.…”
