New techniques in field measurement and gamma spectrometry results processing

Continuous measurement during slow walk along the profile while carrying the probe by hand and reading out the measured values at the end of the measuring interval is the method of mapping and measuring complex regional profiles. The method was compared with that of point measurement used so far. The new method shows a smaller error of uranium and potassium determination while its poorer geometrical conditions during measurement represent a constraint. The application of data processing allows calculating the radioactive element concentration fields using statistical methods. (M.D.). 2 refs., 4 tabs., 5 figs
