TL and EPR studies of CaSO4:Dy phosphor to investigate its efficacy in measurement of food irradiation dose at sub-ambient temperatures
TL;DR: In this article, the effects of sub-ambient temperatures of irradiation and dose response of CaSO 4 :Dy phosphor was investigated and the irradiation dose in the range 0.5-7.0 kGy was chosen to meet the requirement of commercial food irradiation at low temperature.

Thermoluminescence, ESR and x-ray diffraction studies of CaSO4 : Dy phosphor subjected to post preparation high temperature thermal treatment
TL;DR: In this article, the effect of annealing on the TL glow curve structure was investigated and it was shown that the glow peak at 240°C reduces, whereas the low temperature satellite peak increases with the increase in the annaling temperature in the range 650°C to 1000°C.

EPR-TL correlation studies on Bi co-doped CaSO4:Dy phosphor.
TL;DR: It was observed that EPR signal intensities reduce drastically in 250 °C annealed phosphor confirming the role of SO(4)(-) and SO(3)(-) types of defect centers in the dosimetric peak.

TL;DR: The paper reports synthesis of a new film dosimeter based on a solvent-free route that showed no signs of inhomogeneous distribution of MR in the PC matrix, which was attributed to the polarity of PC.

Melt-compounded composites of ethylene vinyl acetate with magnesium sulfate as flexible EPR dosimeters: Mechanical properties, manufacturing process feasibility and dosimetric characteristics
TL;DR: The dose response of the EPR signal of the composites was studied in the dose range 3Gy-4kGy and found to be linear between 18Gy and 4kGy.
