Exponential growth of the dose response curve above 1 k Gy and saturation for doses above 20 k Gy was observed.
For doses lower than 1 k Gy the dose response curve has a linear character.
It is very apparent in tooth enamel below doses of 1 Gy, it has been observed in certain fossil teeth in a very prominent way and also in irradiated food containing bone (e.g., frog legs).
The trapped electrons form para-magnetic centers and give rise to certain signals that can be detected under an ESR spectrometry.
The amount of trapped electrons corresponds to the magnitude of the ESR signal.
Computer Resolution Enhancement Method was applied to the complex spectra.
Some of the γ-induced EPR signals were attributed to CO2 − and CO3 3− paramagnetic centres.
The ancient settlement Hippos, situated on the east shore of the Sea of Galilee, functioned from the 3rd cent.
