“…The findings indicated that CaSO 4 :Mn demonstrated greater sensitivity to radiation in TL compared with CaF2:Dy, CaF2:Mn, and CaSO 4 :Dy. However, the TL glow curve of CaSO 4 :Mn exhibited a fading of 75% from its initial value after 28 days [11]. Utilizing the precipitation technique, calcium sulfate (CaSO 4 ) samples doped with terbium (Tb) and europium (Eu) were effectively synthesized [12].…”

In this work, (99 − x)CaSO4‐Dy2O3–xEu2O3, (where x = 0, 0.05, 0.1, 0.2, 0.3, 0.4, 0.5) thermoluminescence phosphors were prepared using a coprecipitation method. The thermoluminescence (TL) dosimetry (TLD) characteristics such as TL sensitivity, dose–response, minimum detectable dose, thermal fading, and the effect of sunlight on the prepared phosphors were investigated. The obtained results indicated that the most sensitive phosphor was obtained at x = 0.05. Large thermal fading of 6% after 1 h and 26% after 24 h from irradiation followed by 71% after 1 month with no additional fading was observed within a time frame exceeding 2 months throughout the remaining duration of the investigation, which also spanned over 2 months. Despite the phosphor's high fading rate, the relative sensitivity of the prepared samples was ~90% compared with TLD‐100. The marked effect of day sunlight was also determined. High dose–response within the low‐dose range from 0.01 to 5 Gy was observed. The obtained results suggested that the synthesized phosphor is well suited for applications involving radiation biology and radiotherapy dosimetry.
