“…LBO and MBO compounds have stood out in dosimetry for their applicability in thermal neutron dosimetry. In general, magnesium tetraborate shows high sensitivity in thermoluminescent dosimetry and lithium tetraborate has high UV transmittance for certain wavelengths [11,12,15,34].…”

“…To aid in the search for TL and OSL based MBO materials that are best suited for individual and clinical monitoring, Table 1 reports characteristics of materials studied in the last two decades. Among the works, three addressed MBO:Dy,Na [14,35,36], another three studied MBO:Dy [37][38][39], three analyzed MBO:Ce,Li [11,34,40], and others studied MBO doped with Mn and codoped with Tb [41], Dy, Ca, Na [42], Dy, Li [34], Mn [43], Cu [43]; MBO-B2O3 as glass [44], Ce [45]; Tb [46]; Gd, Li [47]. Concerning LBO, in five works, this material was doped with Cu [7,9,21,48,49], undoped LBO was studied by [9,25], and doped with Ag by Ozdemir et al [25] (Table 2).…”

“…As observed in Tables 1 and 2, MBO samples doped with Ce, Li [11,34], Dy, Ca, Na [42], Dy, Li [34], Dy [50], Mn [43], Cu [43], Ce [45], Gd, Li [47], and LBO doped with Cu [7,49] were exposed to beta radiation. Among these, the one that was best for personal and clinical dosimetry is LBO:Cu [49], as it showed a linear dose response between 10 -3 Gy and 10 3 Gy, LDD of 20 µGy, and fading around 10% over 90 days.…”

“…Ce, Li [34], Mn [43], and Cu [43] exhibited luminescence with a linear dose response and fading less than 10% for up to three months storage, these same studies did not investigate the LDD and reproducibility of the TL/OSL emission. Similarly, MBO doped with Dy [50] exhibited a luminescence with a good linear dose response, but the study did not investigate the LDD, fading, or reproducibility of the TL signal.…”

Thermoluminescent (TLD) and optically stimulated luminescent dosimeters (OSLD) are essential in radiation dosimetry. Such dosimeters can be easily transported due to their small size and can be used in in vivo dosimetry and anthropomorphic simulations. In this work, the dosimetric properties of Li2B4O7 and MgB4O7 compounds were evaluated based on their response to the applied stimulus, whether thermal or optical. The linear dose response range of the luminescent signal, its fading, the lowest detectable dose, and reproducibility are important parameters in determining a good dosimeter for clinical and personal dosimetry. Therefore, the objective of this work was, based on studies performed by other authors on dosimetric characterizations of doped a codoped Li2B4O7 and MgB4O7, to point out those compounds with the greatest potential for applications in personal and clinical dosimetry using TL and OSL techniques. Considering the results described in other works, the materials that stood out for use in personal and clinical dosimetry were Li2B4O7:Cu and MgB4O7:Dy,Na. In several of the reported studies, no data related to LDD, fading and reproducibility of the luminescent signal of the investigated compounds were found. Therefore, there are many possibilities for investigations into these two types of compounds for the purpose of their use in personal and clinical dosimetry. Further studies will provide a broader scientific basis for choosing appropriate dosimetric materials for these applications.

“…Indeed, two-photon excited fluorescence (TPEF) [5] combined with SHG imaging provides extremely promising bioprobes [6][7][8], such as those for the identification of early nodules in calcified aortic-valve disease [9]. The detection of light is also fundamental in the field of ionizing radiation detection and measurement [10], where prompt radioluminescence and optically stimulated luminescence are widely used for field characterization and dosimetry [11][12][13]. More recently, the detection of light scattered by neutron-induced bubbles inside superheated emulsions has been described as an efficient read-out system [14,15].…”

The detection of low-intensity light is a crucial issue in many aspects of science and technology. So far, the solution has involved extremely delicate and somewhat bulky devices, the photomultiplier tubes, providing high sensitivity but suffering from fragility and susceptibility to interference. The silicon photomultiplier (SiPM) is a solid-state photon detector that provides a new solution for a wide range of photometry applications in fields as diverse as medicine, biology, environmental science, chemistry, physics, and nuclear physics. SiPMs are on a par with conventional photomultiplier tubes (PMT) in terms of internal gain and photon detection efficiency, while they are undoubtedly superior in terms of mechanical robustness, compact size, electronic stability, low power consumption, and affordability. Our group has long been involved in ionizing radiation measurements based on light emitting sensors both for industrial nuclear technology applications and for hybrid diagnostic imaging techniques. In both cases, SiPMs offer the unquestionable advantages described in this review.
