“…The details of the experimentally measured dose response depend on a great number of instrumental, radiation field and material parameters [17]. Similar feature of dose response was found in TL materials and lies in the dependence of the supralinearity on ionisation density, i.e., on gamma ray energy and on the type of radiation.…”

“…The substantial signal response has a trade-off in lowering the working radiation range of the devices. The γ-radiation-induced changes in the electrical properties of all the samples were found to be similar to the dose response of most materials used in thermoluminescence (TL) dosimetry [17]. They usually show a linear, then supralinear, followed by saturating response and further increase in dose leads to their damage.…”

“…Similar feature of dose response was found in TL materials and lies in the dependence of the supralinearity on ionisation density, i.e., on gamma ray energy and on the type of radiation. The value of maximum supralinearity rapidly decreased with decreasing gamma ray energy: for 1.25 MeV gamma rays in LiF:Mg,Cu,P showed no supralinearity [17]. The difference in the properties of the materials used emerges as reasonable explanation to the changes of supralinear region in dependence of electrical parameters on radiation dose.…”

Thick films of Nickel oxide (NiO) in the form of pn-junctions and planar structures with interdigitated electrodes were investigated for γ-radiation dosimetry purposes. Samples were fabricated using the thick film screen-printing technique. All devices were exposed to a disc-type 137 Cs source with an activity of 370 kBq. They showed an increase in the values of current with the increase in radiation dose up to a certain level. Performance parameters of the devices, such as sensitivity to γ-radiation exposure and working dose region, were found to be highly dependant on the composition of the materials used.

“…f(D) max 3-5 for 60 Co gamma rays decreasing to 1.8 for 20 kV p X rays ( Figure 7). This dependence of f(D) on photon energy is attributed to the competition between localised and de-localised recombination in the UNIM (4,29) and motivated the development of modified TST (MTST) (14,15) in which it is required that f (D) be measured with photon or electron energies that create a secondary electron energy spectrum approximately matched to the HCP-generated electron spectrum.…”

Thin films of Tellurium dioxide (TeO2) were investigated for γ-radiation dosimetry purposes. Samples were fabricated using thin film vapour deposition technique. Thin films of TeO2 were exposed to a 60Co γ-radiation source at a dose rate of 6 Gy/min at room temperature. Absorption spectra for TeO2 films were recorded and the values of the optical band gap and energies of the localized states for as-deposited and γ-irradiated samples were calculated. It was found that the optical band gap values were decreased as the radiation dose was increased. Samples with electrical contacts having a planar structure showed a linear increase in current values with the increase in radiation dose up to a certain dose level. The observed changes in both the optical and the electrical properties suggest that TeO2 thin film may be considered as an effective material for room temperature real time γ-radiation dosimetry.
