Cadmium Sulphide (CdS) thin film was prepared using pyrolytic spraying technique and then irradiated at varied gamma dosage. The CdS thin film absorption before gamma irradiation was 0.6497. Absorbed doses were computed using standard equation established for an integrating dosimeter. The plot of absorbed dose against gamma radiation- induced change in absorption is linear. A calibration curve for the development of a prototype cadmium sulphide – based gamma radiation dosimeter was proposed.
