Thermoluminescent Detectors of High-Density Ionizing Radiation

Ensuring radiation safety of medical examinations using thermoluminescent dosimetry

“…To carry out dosimetric control, TLD-K thermoluminescent detectors based on SiO2 (chips 3×3 mm, thickness 0.5 mm) were used [11,12].…”

“…To measure the absorbed dose in a certain medium, it is necessary to use materials as radiation detectors that are closest in their physicochemical characteristics to the parameters of the medium in which the absorbed dose is to be measured (Zeff is the effective atomic number of the detector, density); a necessary condition is to ensure electronic equilibrium (Electronic equilibrium is a state in which the absorbed energy in a given volume of the medium is equal to the total kinetic energy of the electrons released by photons in the same volume) in the detection system. The closer the characteristics of the medium and the detector, the more accurate the dosimetry will be [11][12][13]. The dose (Gy) measured in different human tissues by tissue-equivalent detectors does not require the use of weighting factors for calculating the equivalent dose and corresponds to the dose in Sv.…”
