Xenon radioisotopes are one of the products of uranium nuclear fission. These radioisotopes are released in the form of gas in the process of dissolving the uranium target to extract 99Mo. This research aims to measure the activity of released xenon radioisotopes. For this, radioxenon is separated from other fission products using activated charcoal and purified after passing through a carbon molecular sieve. Pure radioxenon is directed into the measurement chamber and determined by an HPGe detector. Calibration of the detector efficiency has been performed via experimental and simulation (using MCNPX27e code) and the difference was less than 22%. In this way, the average activity of 100 cc of radioxenon gas at the moment after irradiation was equal to 54225 ±2272 Bq.
