“…Moreover, it was reported that the dose response behavior and the linearity range of CaF 2 :Dy were significantly affected by the variation of the particle size, showing that the particle size of 65 nm increased the upper limit of detection to 12 kGy, from the previous 1 kGy at the 140 nm grain size. 49 These data suggest that it could be a good dosimeter for high-dose applications when considering the proper TL dosimetry features, particularly the linearity over a large range of dose responses, and up to very high absorbed total dose.…”

There are a wide range of applications with ionizing radiation and a common theme throughout these is that accurate dosimetry is usually required, although many newer demands are provided by improved features in higher range, multi-spectral and particle type detected. Today, the array of dosimeters includes both offline and online tools, such as gel dosimeters, thermoluminescence (TL), scintillators, optically stimulated luminescence (OSL), radiochromic polymeric films, gels, ionization chambers, colorimetry, and electron spin resonance (ESR) measurement systems. Several future nanocomposite features and interpretation of their substantial behaviors are discussed that can lead to improvements in specific features, such as (1) lower sensitivity range, (2) less saturation at high range, (3) overall increased dynamic range, (4) superior linearity, (5) linear energy transfer and energy independence, (6) lower cost, (7) higher ease of use, and (8) improved tissue equivalence. Nanophase versions of TL and ESR dosimeters and scintillators each have potential for higher range of linearity, sometimes due to superior charge transfer to the trapping center. Both OSL and ESR detection of nanomaterials can have increased dose sensitivity because of their higher readout sensitivity with nanoscale sensing. New nanocrystalline scintillators, such as perovskite, have fundamentally important advantages in sensitivity and purposeful design for key new applications. Nanoparticle plasmon coupled sensors doped within a lower Zeff material have been an effective way to achieve enhanced sensitivity of many dosimetry systems while still achieving tissue equivalency. These nanomaterial processing techniques and unique combinations of them are key steps that lead to the advanced features. Each must be realized through industrial production and quality control with packaging into dosimetry systems that maximize stability and reproducibility. Ultimately, recommendations for future work in this field of radiation dosimetry were summarized throughout the review.

“…Traditional and commercial TL dosimetric phosphor systems have been designed, which provide high sensitivity and low fading and have been put to successful operation. However, the dose range of these traditional phosphors is normally not over 100 Gy, 7,9 while higher doses need to be measured in technological and medical applications; for example, the sterilization of medical products, and irradiation of food products. This property of linear behavior up to very higher doses makes the NaGdF 4 :3% Tb phosphor useful for its application in estimating high exposures of gamma rays, high-radiation dose dosimetry and other applications.…”

“…CaSO 4 :Dy (TLD-900), LiF-based phosphors such as LiF:Mg,Cu,P (LiF-TLD 700H), LiF:Mg,Ti (TLD-100), Li 2 B 4 O 7 :Mn (TLD-800), CaF 2 :Dy (TLD-200), Al 2 O 3 :C, are efficient and commercially available phosphors. 2,[8][9][10] However, owing to the increasing use of the TL technique, efforts are still being made to improve the TL characteristics and sensitivity of phosphor materials either by thermal treatment or by impurity doping. Attempts are also being made to develop new phosphor materials with improved TL characteristics.…”

“…[27][28][29][30][31][32] In the last few decades, several nanomaterials were investigated for their application in TL-based high-dose radiation dosimetry as nanophosphors give better linear dose-response in highdose (∼kGy) region. [33][34][35] In addition, the present study will also report the calcination temperature-dependent tunable dual application of the material in the field of PL and TL. It was shown that, at low temperature (1273 K), Al 5 BO 9 : Mn, Li can be used as a suitable TL dosimeter due to the dominance of the Mn 2+ center.…”

A near tissue equivalent (Zeff = 10.8) and wide bandgap (Eg = 5.95 eV) Al5BO9: Mn, Li nanophosphor was synthesized by facile gel‐combustion (GC) method, and structural characterizations were performed by XRD, infra‐red, transmission electron microscopy, energy‐dispersive spectra, diffuse reflectance UV–visible spectra, and PL studies. Thermoluminescence (TL) study of Al5BO9: Mn, Li revealed the dosimetry glow peak at 542 K, which was absent in undoped Al5BO9 indicating the importance of Mn dopant. The highest TL response was obtained for the lowest studied dopant concentration (0.1 mol% Mn) that was attributed to the concentration quenching phenomenon. The material is highly reusable with low fading (<10%) up to 110 days. TL response for both thermal neutron and gamma radiations showed excellent linearity within 5 × 109–3 × 1011 n/cm2 and 30–5000 Gy, respectively. These studies suggested promising potential of Al5BO9: Mn, Li nanophosphor in clinical neutron dosimetry and food irradiation dosimetry applications. Based on the variation of calcination temperature, strategy toward dual application, namely, radiation dosimeter and red‐light emitting phosphor of the material was established. For a better understanding of the TL process, various kinetic parameters like activation energy (E), order of kinetics (b), and frequency factor (s) were evaluated using different methodologies, and the results were found to be in good agreement.
