Disintegration rate measurement of (182)Ta.
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.
