摘要：
In the present paper the advantages of a I-129 standard are shown which has been used for the experimental verification of the everyday constant response of the gamma counter used for the measurement of I-125, as well as for the determination of the counting efficiency. This value was also determined by a coincidence technique. The results obtained by either method were compared and found to be equal. Some theoretical considerations concerning the utilized equations are analyzed.
