Specific advantages of the method

Due to the penetrating power of photons in material media, photon activation can be used for overall analysis of samples, of any form, weighing between a few mg and several grams. 

In addition, standardization is simple and direct and does not require reference materials produced elsewhere. 

Interferences by competing nuclear reactions can be significantly reduced, or even completely eliminated, by the suitable choice of the maximum energy of the gamma photon beam. 

Furthermore, the substances Investigated can be activated through the walls of sealed containers (sealed ampoules, metallic etc). This offers a considerable advantage for the analysis of highly reactive metals (e.g. Li, 

Finally, if required, the samples can be cooled easily during irradiation, with water, liquid nitrogen or any other cryogenic fluid.
