DETECTION LIMITS OF ABSORBED DOSE OF IONI ZING-RADIATION ON MOLLUSCANSHELLS AS DETERMINED BY EPR SPECTROMETRY

The exposure of waters to ionizing radiation from radionuclides stored in concrete containers or freed in nuclear accidents or underwater er uption might be difficult to be proved, when currents, rains, exchange of water displace sand soils or rocks in the buttom. Ionizing radiati on evokes stable paramagnetic centers in the crystalline lattice of mi neral components in bones as well as in exoskeletons of most mollusca, which are detected by the EPR spectroscopy and could be used as an in dicator of the exposure to the action of radiation during prolonged pe riod of time.
