The purpose of this study was to analyze in a wavelength range from 400 to 500 nm, the additional absorption bands-like in the characteristic net absorption spectra of the EBT3 radiochromic films irradiated with 6 MV X-ray in a dose range from 0 to 10 Gy through a theoretical model describing the interference effects of a Fabry-Perot cavity containing poly-DCHD.
