“…This means that the dosimeter response is only slightly affected by light and the film can be utilized in routine analysis without any further protection from laboratory lights. This behavior is similar to that of HDBU-PVA films analyzed at 610 nm: the response in the dark or under light conditions increased by approximately 3% within 24 h after irradiation, and then remained stable until the end of the storage period (Soliman et al, 2014b). The response in the dark of better performing PCDA-PVB film types increases by 4% in the first 24 hours following irradiation, then grows more slowly with time (Abdel-Fattah and Soliman, 2017).…”

“…These results are similar to those obtained previously for PCDA-PVB film dosimeters (Abdel-Fattah and Soliman, 2017): the response of PCDA-PVB films varied by 4-6% in the same RH range upon analysis at 670 nm. In addition, PVA films containing the HDBU monomer showed a similar trend: the change in response with RH was within about 2% (Soliman et al, 2014b).…”

“…Irradiation of a HDDBU-PVA film under oxygen reduces the film response by 16-23%, thereby demonstrating the slow-down of the light-induced polymerization process by oxygen. Nevertheless, the response was negligibly affected by relative humidity (RH) during irradiation: a 2% change was observed upon increasing the RH from 0 to 94% (Soliman et al, 2014b). In addition, a radiation-sensitive film of poly(hexa-2,4-diynylene adipate) (PHDA) in PVB was investigated for dose estimation in the range of 0.5 to 60 kGy (Soliman et al, 2018a).…”

Gamma-irradiation processes are very important tools for minimizing microbial load in dry food, inhibiting the proliferation of T-lymphocytes in blood, and for the sterilization of medical devices. To this end, a composite film dosimeter made of a radiation-sensitive monomer, 1,10-bis(diphenylamino)-4,6-decadiyne (DPD), embedded in poly(vinyl alcohol) was prepared using an automatic film applicator system. This polymeric film undergoes a color change from pale yellow to deep orange upon γ-irradiation due to topochemical polymerization of the DPD monomer. This color change is proportional to the amount of absorbed dose. With increasing absorbed doses, gradual disappearance of the  C≡C Raman band of the C≡C-C≡C chemical groups is observed, and new  C≡C and  C=C bands ascribed to the formation of a polydiacetylene with an enyne structure are detected. The irradiated films exhibited two absorption maxima at 470 and 502 nm as measured by UV-Vis spectrophotometry, and the intensities of these bands increased with increasing absorbed doses. Analysis of these films using a high-resolution flatbed scanner (2400 dpi) showed an increase in optical density with increasing absorbed doses up to 269.1 kGy. Stability checks revealed that the irradiated films underwent an increase in the color intensity by ≈3.1% over 50 days of storage. In addition, relative humidities in the range 0-75.3% had a limited impact on the dose response of the films, with a 4% change in this range. The uncertainty (2σ) on dose measurements using the scanner was 4.46%, demonstrating the effectiveness of this film dosimeter for radiation monitoring up to 296.1 kGy.

“…Together with polymer gel dosimeters, which rely on the radiation-induced polymerization of their comonomer components [3,4], Fricke gel (FG) dosimeters are good candidates for 3D dose assessment in biological materials because of their tissue equivalence [5]. Indeed, their effective atomic number and density are similar to those of water and soft tissue [6].…”

This article presents a novel radiochromic film for selective detection of low-medium (0-10 kGy) gamma radiation ( 60 Co) doses. This dosimeter is based on a printed fluorescent multilayer structure comprising a paper substrate having layers of copper phthalocyanine (DY220) (a green emitter material) on the bottom, and layers of poly[2-methoxy-5(2 0 -ethylhexyloxy)-p-phenylenevinylene] (MEH-PPV) (a green-light absorber, red emitter, and radiation sensitive polymer) on the top. The effect of gamma radiation on the optical properties of DY220/MEH-PPV was described: it was observed as a strong correlation between radiation dose and fluorescent, color coordinates for CIE (1931) chromatic diagram, and Pantone color reference of the dosimeter. The rate of these changes can be altered by manipulation of top-bottom layers to represent easily the radiation dose to be determined in a wide range. This versatile dosimeter has many uses in the field of food radiation for monitoring, quality assurance, and control of the gamma radiation process.
