“…TTC was chosen as a representative of tetrazolium salts, which showed a response to UV irradiation as reported elsewhere [17]. Pluronic F-127 is approved by the US Food and Drug Administration (FDA) as a nontoxic copolymer [17], which provides a colourless and transparent hydrogel matrix that does not change colour after UV irradiation [17,18]. Depending on ambient temperature and concentration, Pluronic F-127 can form an aqueous solution or a physical gel.…”

“…Due to the non-toxicity of Pluronic F-127 and trace amounts of the radiochromic compound, the dosimeter would not be a threat to the aquatic environment. So far, radiochromic hydrogels with Pluronic F-127 have been studied as 1D, 2D, and 3D dosimeters for UV and ionising radiation dose measurements, such as (i) textile dosimeters printed with NBT-Pluronic F-127 pastes [16]; (ii) LCV-Pluronic F-127; (iii) TTC-Pluronic F-127; (iv) LMG-Pluronic F-127 [17]; and (v) NBT-Pluronic F-127 capsules [18].…”

This work reports on the new chemical dosimeters for UV radiation dose measurements on coral reefs and in seawater. The proposed dosimeters can measure the actual dose of UV radiation, which consists of 95% UVA and 5% UVB radiation, unlike the currently-used radiometers in marine and ocean waters that measure the dose of UVA and UVB radiation separately. The dosimeters are composed of water, poly(ethylene oxide)-block-poly(propylene oxide)-block-poly(ethylene oxide) (Pluronic F-127) as a gel matrix, and 2,3,5-triphenyltetrazolium chloride (TTC) as a UV radiation-sensitive compound. In the work, the dosimeters were characterised in terms of their response to the dose of UV radiation depending on the TTC concentration and the irradiation and storage conditions of the dosimeters. The stability of the dosimeters over time was also examined. The obtained results indicate that the TTC-Pluronic F-127 dosimeters can be used to measure absorbed doses of UV radiation in the saltwater environment. The developed dosimeters with a concentration of 0.1% TTC can be used up to 5 J/cm2, which predisposes them to UV radiation measurements at a depth of more than 10 m in sea and ocean waters in 10-min intervals during all months throughout the year.

“…[40] Until now, Pluronic F-127 has been used both in Fricke-based 3D gel dosimeters, other 3D radiochromic gel dosimeters, 3D polymer gel dosimeters, and various applications. [10][11][12][13]27,29,[40][41][42]60,61,[76][77][78][79] Pluronic F-127 improves the thermal performance of the dosimeter in the temperature range above ≈30 °C where the physical gelatine gel dissolves. Some researchers have addressed the problem of the stability of 3D gel dosimeters at elevated temperatures.…”

3D chemical dosimetry of radiotherapy is an interdisciplinary research related to medical physics, polymer and radiation chemistry, photochemistry, organic chemistry, computer science, oncology, materials engineering, and automation technology. It consists of a 3D high resolution tissue equivalent dosimeter, high resolution 3D reading, and software packages for fast processing of 3D measurement data. Research on 3D radiotherapy chemical dosimetry has been going on for almost forty years, starting with the first proposal of a 3D dosimeter -Fricke dosimetric solution in a physical gel matrix with magnetic resonance imaging (MRI) reading to record the spatial dose distribution. [1] Further research concerned both Fricke-gel dosimeters and other systems, such as polymer gel dosimeters, radiochromic gel and plastic dosimeters, and flexible dosimeters. Many dosimetric compositions have been proposed. As a general rule, each new 3D dosimeter has a specific acronym, usually derived from its components. Examples of 3D polymer gel dosimeters are as follows (the acronyms are associated with example references): BANG, [16] PAG, [17] PAGAT, [18] nMAG, nPAG, [19] MAGIC, [17,20] MAGIC-f, [21] NIPAM, [22,23] VIPAR, [24] VIP (VIPAR nd ), [25] VIC, [26] VIC-T, [26] VIP3-Pluronic F-127, [27,28] PAGAT2-Pluronic F-127, [29] PAB-IG nx , [14,30,31] NHMAGAT, [32] MAGADIT, [33] NMPAGAT. [34] Examples of 3D radiochromic dosimeters are as follows: PVA-GTA-XO-Fricke, [35,36] PVA-GTA-MTB-Fricke, [37] Fricke-XOgelatine, [38] Fricke-XO-Pluronic F-127, [10,13,39] TTC-Pluronic F-127, [40] NBT-Pluronic F-127, [41,42] KI-PVA, [43] KI-Pluronic F-127, [12] LCV-gelatine; [44] and 3D plastic radiochromic dosimeter: PRESAGE. [3,45,46] 3D flexible dosimeters have also been proposed: LMG-silicone, [47,48] FlexyDos3D, [49] as well as 3D lung-mimicking dosimeters: PAGAT-2-Pluronic F-127 foam, [11] foam based on methacrylic acid-gelatine infused with sodium dodecyl sulphate surfactant, [50] and methacrylic acid-gelatine gel with expanded polystyrene spheres. [51] It should be mentioned that alternative 3D reading techniques to MRI were also investigated, including computed tomography (CT), [22,23,52] ultrasonography, [53][54][55] and optical computed tomography (optical CT). [56,57] It has been shown that 3D dosimetry data This work reports on a new type of combined radiochromic ionizing radiation dosimeter for radiotherapy. The LCV-Pluronic F-127 serves for this purpose, which is a leuco crystal violet embedded in a physical hydrogel matrix of poly(ethylene oxide)-block-poly(propylene oxide)-block-poly(ethylene oxide) (Pluronic F-127) with additives. This dosimeter responds to ionizing radiation by developing a blue color with an intensity related to the radiation dose. The LCV-Pluronic F-127 dosimeter is improved for lower temperature stability by adding sodium chloride (NaCl). Subsequently, a method for manufacturing the LCV-Pluronic F-127 lung mimicking dosimeter is proposed. Next, the LCV-Pluronic F-127 3D composite dosimeter is elaborated, which cont...
