Due to the special interest in applications on radiotherapy, radiobiology, analysis and material testing, in the last years the Bucharest U-120 classical variable energy Cyclotron was employed as an intense source of fast neutrons produced by 13.5 MeV deuterons on a thick beryllium target, mainly for radiobiological and archaeometrical studies. Energy spectra and yields, average energy and irradiation doses were determined using time-of-flight, multiple foils and thermoluminescent detector methods. Studies on liver chromatin structure modifications and on some archaeological Greek objects; composition using FNAA are presented.
