Radiation-induced changes on some physical parameters of gelatine for protection-level dosimetry utilization

The induced effects of gamma and thermal neutrons of respective absorbed dose ranges 10-2-103 Gy and 10-500 mSv, on the physical changes of the gelatine electrical resistivity, hardness, and luminescence intensity (RPL), have been investigated. The results indicated that the hardness indentation number and RPL luminescence emission intensity increase with increasing gamma and neutron absorbed doses, while the electrical resistivity decreases. The dose sensitivity relation with these induced physical changes is beneficial for dosimetric utilization. The changes are described by semi-empirical regressions formulae. (author)
