A Plasma Focus is being developed for breeding Short Lived Radionuclides. The different radiation protection issues and concerns posed by the machine once in operation are analysed and discussed. Activation is shown to be totally negligible and likewise neutron emission is found to pose no concern at all. The only source of radiation risk is found to rest in the radionuclides produced, F-18 and O-15, generating a peak exposure of 1.114 Sv/y at the distance of closest approach of 2.5 m. Shielding to protect against this hazard is calculated to be 5 cm Pb or 54 cm concrete for the operation area, 5.5 cm Pb for the transportation flask.
