摘要： The instant invention relates to a method to compensate for extraneous radiation caused by the effects of intermittent active radiation sources (not effects due to cosmic or terrestrial radiation) that can cause errors in radiation measured values. For the purposes of suppressing these extraneous radiation effects in radio-active measuring methods, the commencement and termination of the extraneous radiation and the attainment of a stable condition in the extraneous radiation are determined. The difference between the measured value (before commencement of the extraneous radiation) and the measured value (on attainment of the stable condition) is determined. The measured value is then reduced by the determined difference for the duration of the extraneous radiation. Since the determined difference corresponds to the change in the measured result brought about by the extraneous radiation, the resultant measured value obtained by this reduction, equals the measured value that would be obtained in the absence of the extraneous radiation.
