Investigation of detergent powder as gamma radiation dosimeter using ESR technique

Detergent powder is one of the most commonly available laboratory materials, which is often used for decontamination. If radiation exposure induced free radicals in this matrix are measurable, it can potentially serve as a retrospective dosimeter under accidental conditions. Therefore work in the study of radiation induced radicals in the detergent powder by electron spin resonance (ESR), were initiated and evaluated for its potential as a ESR dosimeter at higher dose ranges. These results therefore suggest that detergent can be used as a possible dosimeter in programmes such as food preservation by irradiation (1 kGy - 10 kGy) and accidental dosimetry at lower dose levels (∼25 Gy)
