Radiation response to gamma-ray absorbed dose in the range of 10 to 750 kGy and neutron absorbed dose in the range of 10 mGy to 700 Gy were investigated using Swedish manufactured silicon diode, type 5422. The results indicated that its sensitivity to gamma-rays is 17.6 m V/kGY up to 60 kGy, and its sensitivity reduces to 10-17 mV/kGy from 70 kGy up to 700 kGy within an error of ±7%, while its response to fast fission neutrons is G7 mV/Gy. Factors affecting dosimeter reading such as dosimeter reading at high temperature, dosimeter annealing and reusability are also studied. The system teas used for gamma-ray and neutron dosimetry around high level gamma-ray source, reactor ducted concrete shield, and it is also examined for reactor core dosimetry.

Proceedings from the general task of nuclear geophysics as a special discipline of applied geophysics, the essential physical problems of nuclear well logging techniques are considered. Particularly, the quantitative connexion between measured value and interesting geologic parameter to be determined are treated taking into account internal and external perturbation parameters, Resulting from this study, the technological requirements for radiation sources and there necessary screening, for detectors, electronic circuitry in logging tools, signal transmission by the cable and recording equipment are derived, and explained on examples of gamma-gamma- and neutron-neutron-logging.
