Dose mapping in gamma chamber using glass plate dosimeter

The quality of radiation-processed (blood, animal, medical and R and D) material is mostly dependent on how accurately the radiation dose has been delivered to the material. Chemical (Fricke, FBX and Ceric-cerous), ESR and TL are few processes on which high dose (kGy range) dosimetry is based. Applications of general-purpose glasses have been reported to for its use as high dose gamma dosimetry using, TL, OD (Optical Density) and spectro-photometric techniques in recent past. The dose distributions in the irradiation volume of gamma chamber are not perfectly homogeneous and variations reported within ± 25%. If dose in-homogeneity within the chamber is not under one's control, at least it should be known for dosimetry correction and uncertainty evaluation in the irradiated samples. Authors have employed general-purpose transparent glass plate for evaluating the dose distribution in any close type gamma chamber and results are presented
