Abstract

This paper presents the findings of a study on dose rate distribution in air and water phantoms, recorded using Gafchromic films. Low energy accelerator with X-ray tube (NALR), a system developed at the National Centre for Nuclear Research (NCBJ), generated by the dose rates. The primary objective of this research was to employ the X-ray tube as a source of X-ray radiation and assess dosimetry techniques using radiochromic films for radiological protection purposes. Gafchromic MD-55-V2 and EBT films were utilized for measurements. Two-dimensional measurements with Gafchromic dosimetry films were compared against ionization chambers AP 2.0 (in water) and PTW-23342 (in air) to validate radiation dose rate distributions. Furthermore, the film response over different days post-exposure highlights the importance of scanning radiochromic films on the first day after exposure.
