Abstract

This paper presents the measured thick target yield of 99mTc from molybdenum sample with 92.2% enrichment in 100Mo isotope via the (p,2n) nuclear reaction channel. The yield was determined experimentally with application of the 11-MeV medical cyclotron Eclipse RD, equipped with a new target assembly developed for solid sample irradiations. The experimental physical yield was measured to be 30.9 ± 1.3 MBq/μAh. This result was compared with theoretical calculations and results of other authors. The features of irradiation conditions that may have an influence on produced activity were studied and analyzed.
