A dosimetric calibration of three types radiochromic films (GafChromicTM HD-V2, MD-V3, and EBT3) was carried out for absorbed doses (D) ranging up to 100 kGy using a 130 TBq Co60 γ-ray source. The optical densities (ODs) the irradiated were acquired with transmission-mode flatbed film scanner EPSON GT-X980. data cross-checked 20-MeV proton beam from azimuthally varying field cyclotron at Resear...
