Abstract:
The purpose of this experiment was to compare the calibration factors for Cs-137 and Co-60 of six radiation measuring instruments in fast five years to evaluate the accuracy of radiation measurements of different instruments. For this comparison, we used survey meters with different type of gaseous ionization detectors mainly GM tube, Proportional counters and ionization chambers.
