“…The TLD film is 2.25 cm x 2.25 cm and made from voxels, each has dimension of 100 µm x 100 µm x 100 µm. Those geometries are depicted in the upper part of Fig 1 . Within the voxels are MgB 4 O 7 doped with 0.5% Dy 3+ (2.56 g/cm 3 ) phosphor powders dispersed by PTFE (C 2 F 4 , 2.2 g/cm 3 ) [21]. The film is attached to human phantom, which is block in shape and consists of two layers: the outer one signifies clothing made from polyethyl terephthalate (PET, C 10 H 8 O 4 , 1.37 g/cm 3 ) and the inner one represents human body in its elemental composition (ICRP Publication 123, 2013) [22].…”

Magnesium borate (MgB4O7) is currently being studied as the material for neutron dosimetry. To become a proper dosimeter, magnesium borate is doped with dysprosium as the activator and PTFE (polytetrafluoroethylene) is used as the binder. To estimate the response of PTFE-bound MgB4O7:Dy for neutron dosimetry, Monte Carlo simulation was conducted by PHITS (Particle and Heavy Ion Transport Code System) software. The simulation consisted of dosimeter film of said materials attached to a simplified human phantom. The amount of PTFE ranged from 50% to 90% and the thickness of the film was varied from 0.5 mm to 2.5 mm. The result showed that this film dosimeter had high response to thermal neutrons and low response to fast neutrons, in contrast with the response of human body. Furthermore, it also suggested that the sample with the highest MgB4O7 content had the lowest absorbed dose due to self-shielding effect while on the thicker film, the effect of self-shielding also reduced the sensitivity of this film dosimeter.

“…Specifically, lithium tetraborate compounds are very effective in the elimination of oxidative stress and provide significant antioxidant activity. Also, it was reported that lithium tetraborate was employed as an advanced application in eye lens dosimetry (Charubala et al 2019). However, the protective or therapeutic efficiency of lithium borate is still limited.…”

Epidemiological studies suggest that acute kidney injury has certain effect on myocardial function. In this study, for the first time, we tested a boron compound namely lithium tetraborate an act as an anti-oxidant and anti-inflammatory agent in ischemia-reperfusion injury. For this, we employed an in vivo rat model with kidney ischemia reperfusion injury to evaluate cardiac injury to clarify the mechanisms of lithium tetraborate. The evaluation of cardiac injury through kidney artery occlusion and reperfusion rat model indicated that lithium tetraborate could (1) reduce oxidative stress-induced endothelial dysfunction; (2) attenuate the inflammatory response of cardiac cells; and (3) alleviate the apoptosis and necrosis of myocytes. In summary, lithium tetraborate demonstrates significant therapeutic properties that contribute to the amelioration of cardiac damage, and it could be a promising candidate for future applications in myocardial dysfunction.

Gamma-ray spectra were measured using a LaBr$_{3}$(Ce) spectrometer during the outage periods, aiming at quantifying the gamma source term of radiation workers’ exposure, at the CANDU nuclear power reactors, for the purposes of eye lens dosimetry. The spectra were measured inside the boiler rooms, of the Bruce Power and Ontario Power Generation (OPG) CANDU nuclear power plants, where workers are exposed to relatively high dose rates radiation fields during the maintenance work. Prior to measurements at the CANDU reactors, the pulse shaping parameters of the gamma spectrometer were optimised for high rates gamma fields, up to an input rates of 120 kcps, in order to accomplish a high output rate with a reasonable energy resolution. In parallel, the response of the LaBr$_{3}$(Ce) detector was characterized by experiments and Monte Carlo simulations. The gamma spectra measured at the CANDU reactors were reported in terms of the gamma-ray fluence rate spectrum. In all measured data, $^{60}$Co and $^{95}$Nb were main contributors of the gamma fields. The measured spectra have been used to calculate the dosimetric quantities of interest: personal dose equivalents H$_{p}$(10) and H$_{p}$(0.07) and eye lens absorbed dose.
