A new experimental setup with a Bridgman-type high-pressure cell in a closed containment allows work with highly radioactive materials. Results of high-pressure, low-temperature resistance measurements of PuSb single crystals in the pressure range of 1 GPa to 25 GPa and at temperatures between 1.3 K and 300 K are presented. With increasing pressure, the Néel temperature and the transition temperature to the ferromagnetic ground state increased. In the pressure range from 10 GPa to 15 GPa the resistance decreased sharply, which was associated with the crystallographic phase transition from the B1 (NaCl) to the B2 (CsCl) structure. The high pressure phase appears to be non-magnetic.
