abstract = "Fotonski snopovi FFF (Flattening Filter Free) terapijskih linearnih akceleratora zbog
bitno redukovane filtracije poseduju i niskoenergetsku komponentu. Aktivacijom
izomernog stanja 115mIn u sredini polja, kao i na njegovim ivicama načinjen je pokušaj
da se uporede spektralne karakteristike standardnih FF i FFF snopova. Merenja su
vršena u snopovima od 6 MeV na dva različita tipa akceleratora. Uprkos činjenici da je
kod obe vrste akceleratora dozni profil polja jednak, saturacione aktivnosti aktiviranih
uzoraka od prirodnog In se veoma razlikuju što ukazuje na značajne razlike u obliku
spektra., Photon beams of FFF (Flattening Filter Free) therapeutic linear accelerator because of
substantially reduced filtration have noticeable low-energy component. With activation
of isomeric state of 115mIn in the middle of the field, and on its edges we made an
attempt to compare the spectral characteristics of standard FF and FFF beams.
Measurements were performed in beams of 6 MeV nominal energy in two different types
of accelerators. Despite the fact that in both types of accelerators have the same dose
profile of beam, the saturation activity of the activated samples of natural In are very
different, indicating significant differences in the form of spectrum.",
