“…Other films were also used to prepare dosimeters, such as polyvinyl butyral with nitro-blue tetrazolium [ 12 ] or methyl red [ 13 ]. In turn, other researchers focused on investigating the radiotherapy dose range (gray range) film dosimeters (radiochromic and thermoluminescent) [ 14 , 15 ]. Examples of such dosimeters are the silver halide film dosimeter (XV and EDR-2, Kodak, Rocheter, NY, USA) and the EBT radiochromic film dosimeter (GafChromic ® EBT, Ashland, Wilmington, DE, USA).…”

This work presents an ecological, flexible 2D radiochromic dosimeter for measuring ionizing radiation in the kilogray dose range. Cotton woven fabric made of cellulose was volume-modified with nitrotetrazolium blue chloride as a radiation-sensitive compound. Its features include a color change during exposure from yellowish to purple-brown and flexibility that allows it to adapt to various shapes. It was found that (i) the dose response is up to ~80 kGy, (ii) it is independent of the dose rate for 1.1–73.1 kGy/min, (iii) it can be measured in 2D using a flatbed scanner, (iv) the acquired images can be filtered using a mean filter, which improves its dose resolution, (v) the dose resolution is −0.07 to −0.4 kGy for ~0.6 to ~75.7 kGy for filtered images, and (vi) two linear dose subranges can be distinguished: ~0.6 to ~7.6 kGy and ~9.9 to ~62.0 kGy. The dosimeter combined with flatbed scanner reading and data processing using dedicated software packages constitutes a comprehensive system for measuring dose distributions for objects with complex shapes.
