Measurement of the activity of (182)Ta sources produced by irradiation at the IPEN research reactor was performed in a 4pibeta-gamma coincidence system by using the extrapolation technique. The measurements were undertaken selecting two windows in the gamma-channel, in order to check the consistency of the results. A Monte Carlo calculation was performed in order to predict the behavior of the observed activity as a function of the 4pibeta detector efficiency and the results were compared with experimental values.
在IPEN研究堆中通过辐照产生的（182）Ta源的活度测量是在一个4πβ-γ符合系统中采用外推技术进行的。测量时在γ通道选择了两个窗口，以检验结果的一致性。进行了蒙特卡罗计算，以预测观察到的活度随4πβ探测器效率的变化情况，并将结果与实验值进行了比较。
