In the checking of radwaste drums, the evaluation of errors related to the random distribution of the radioactive source inside the radwaste drums is concerned. The extreme assessments were made based on the assumption that radioactive sources are in the place causing the largest error. This does not reflect reality. This paper presents an evaluation method of systematic error of the measurement technique using two identical detectors based on the assumption that the distribution of radioactive sources in the waste drums is random. The results show that in most cases systematic errors are much smaller than that of the deterministic method having the extreme assessments.
