THE COMPUTER CODE MAR FOR CALCULATING THE ACTIVITY OF RADIOACTIVE SAMPLES IN MARINELLI BEAKERS

The Monte Carlo code MAR was developed to calculate the peak efficiency of Ge detectors to voluminal sources of Marinelli-type shapes. Results evaluated with the present method are compared with experimental data. The applicability of the MAR code was demonstrated in a survey which included quantitative isotopic analysis of trace radioactivity in many water and mud samples.
