“…For both operational dosimetry quantities, H p (10) and H p (0.07), it can be concluded that D2 shows improvement in terms of relative energy response, which is important for its use in low-energy photon fields similar to N-40. The comparison of energy dependence of D1 and D2 with the results presented in the research by Luo et al (2017) showed that LiF:Mg,Cu,P material placed in holder 8850 has a less pronounced energy dependence for the low energy photons, with the maximum values not greater than 20%.…”

“…Previous research shows that LiF:Mg,Cu,P has a smaller change in energy and angular response (N-40, 60°) under irradiation conditions—up to +17 % for H p (10) (Luo et al 2017). If only angular dependence is considered, change in relative response is similar for LiF:Mg,Cu,P and D1 [approximately 35% increase from (N-40, 0°)].…”

“…If only angular dependence is considered, change in relative response is similar for LiF:Mg,Cu,P and D1 [approximately 35% increase from (N-40, 0°)]. If energy and angular dependence are observed together, LiF:Mg,Cu,P displays less pronounced overresponse since the energy response for (N-40, 0°) is underestimated (Luo et al 2017).…”

“…Extensive type testing regarding the effects of different influence quantities (i.e., radiation, environmental, and mechanical) was done by Luo et al (2017) on a passive dosimetry system comprised of dosimeters with LiF:Mg,Cu,P detectors, the 8850 holder model (Thermo Fisher Scientific, Waltham, MA), and the 8800 Plus TLD reader (Thermo Fisher Scientific).…”

A need for detailed testing of individual monitoring systems used in accredited service at the Vinca Institute of Nuclear Sciences was recognized following changes in individual, workplace, and environmental monitoring passive dosimetry systems acceptability criteria stated in IEC 62387:2020 and changes related to reference fields used in radiation protection defined in ISO 4037:2019. Reliability and accuracy of dosimetry data acquired by passive dosimetry systems used for individual monitoring is assured by carrying out type tests. In this manner, the effects of different radiation influence quantities are examined. Passive dosimetry systems comprised of an LiF:Mg,Ti (TLD-100) detector card placed in two different holder models (8814 and 8850) and the Harshaw TLD Model 6600 Plus Automated Reader were tested. Type tests were done in an extended range of photon energies from 40 keV up to 1.25 MeV, angle of incidence values of ±45° and ± 60° for both vertical and horizontal dosimeter orientation, and in the dose range from 0.05 mSv to 1 Sv. Both dosimetry system configurations perform in line with IEC 62387:2020 within mandatory range for tested influence quantities. Dosimeters that use the 8850 holder type showed less pronounced energy and angular dependence of the response in the low-energy range.

“…cesium-137 (IG-13) and cobalt-60 point sources were used for higher photon energies exposures. All the irradiations were carried out by Air Kerma with the standard procedure mentioned in IEC 62387, [35,36] at room temperature at Secondary Standards Dosimetry Laboratory (SSDL), PINSTECH, Islamabad Pakistan, to obtain a consistent reference condition at a known dose. A standard test dose of 500 mGy was used for studying the various properties of the samples as further described.…”

Thermoluminescence (TL) and extended dosimetric characteristics of naturally occurring sodium chloride (NaCl) salt were studied. Pellets were prepared from mined crystalline salt obtained from Khewra Salt Mines, Pakistan and irradiated from 1 mGy to 10,000 mGy using cobalt-60 gamma source. The TL response showed two dominant peaks around 125 C and 230 C, respectively, at low doses, with an additional peak in between at doses beyond 300 mGy. A linear and supra-linear TL response was observed between 1 mGy-100 mGy and 100 mGy-10 Gy dose ranges, respectively.During the first 24 h post-irradiation, the TL intensity dropped by 20%. A maximum angular dependence of up to 50% was observed between 0 to 360 . For photon
