Abstract
This paper presents an alternative for determining the activity discharged 131I in the dumping of nuclear medicine facilities that perform therapy, a mount for the in situ determination of liquid discharges of 131I by spectrometry technique developed gamma high resolution using hyperpure germanium detector. The assembly constructed simulated actual discharge conditions in an installation, in order to fine-tune the measurement system used, determining the parameters of
efficiency, uncertainty and detection limit.
