Abstract

This study investigates the possibility of achieving unity energy response using the very sensitive CaSO4:Dy/Teflon thermoluminescent detector at photon energies below 100 keV. Accurate measurements for the energy responses were carried-out using ultra thin, 3 micron thick, TLD discs with average grain size of about 3μm. The present work shows that the experimental reduction factor for the 15 % phosphor loading with average grain size of 3 μm is in good agreement with the calculation based on the cavity theory but at grain size of 1.0 μm. This indicates that the cavity theory is underestimating the real experimental reduction factor in the energy response. The present work expect that unity energy response can be achieved with grain size of about 1 μm.
