Photonuclear physics is dominated by a giant resonance phenomena occurring in the photon energy range of ~10 to ~30 MeV. To excite these resonances electron LINACs can be used as bremsstrahlung photon generators. Interactions of these photons with target material cause nuclear transmutations, which results in numerous applications. One such application is radioisotope production. This talk will bring up the benefits of photonuclear production of radioisotopes in comparison with currently used reactor-based methods. As an example, photonuclear production of 67Cu, one of the most promising beta-emitting isotopes for radioimmunotherapy, will be reviewed. Another application of photonuclear transmutation is photon activation analysis (PAA), which is a non-destructive, highly sensitive analytical technique. PAA allows one to measure trace amounts of impurities in geological, archaeological, environmental and other types of samples. Computer simulations and experimental results for both applications obtained at the Idaho Accelerator Center (IAC) will be presented.
