摘要

The procedure followed by the Nuclear Metrology Laboratory, at IPEN, for the primary standardization of 99mTc is described. The primary standardization has been accomplished by the coincidence method. The beta channel efficiency was varied by electronic discrimination using a software coincidence counting system. Two windows were selected for the gamma channel: one at 140keV gamma-ray and the other at 20keV X-ray total absorption peaks. The experimental extrapolation curves were compared with Monte Carlo simulations by means of code ESQUEMA.
