The first on-line tests of the ion sources to provide radioactive ion beams of {sup 69,70}As and {sup 17,18}F for the Holifield Radioactive Ion Beam Facility have been performed using the UNISOR facility at HRIBF. For {sup 70}As the measured efficiency is 0.8 {+-} 0.3% with a hold-up time of 3.6 {+-} 0.3 hours as measured with {sup 72}As at a target temperature of 1,270 C. For {sup 17}F the efficiency for Al{sup 17}F is 0.0024 {+-} 0.0008% with a hold-up time of 16.4 {+-} 0.8 m as measured with Al{sup 18}F at a target temperature of 1,470 C
