The 1-3 micrometers short wave IR detector has many applications in astronomy, optical radar and optical communications. The devices applied in air will inevitably influenced by all kinds of particle irradiation. So it is very important to study the influence of irradiation to the device performance. In this paper HgCdTe photovoltaic devices with different wavelengths were irradiated by gamma rays under different doses. The changes of their response spectrum, I-V characteristics, photo signal, noise, responsivity and detectivity were studied. It is observed that there is no noticeable change in the peak and cut-off wavelength after 22.7Mrad gamma irradiation, but the responsivity and detectivity decreased within a large extent. The results were analyzed at last.
