Abstract

This paper considers secondary neutrons contribution to the yield of 99mTc obtained from the thick Mo-sample via (p,2n) nuclear reaction channel. The physical yield was determined experimentally using 11-MeV cyclotron Eclipse RD with application of the new target assembly developed for solid sample irradiations and appeared to be 30.9 ± 1.3 MBq/μAh. The neutron flux over the sample was analyzed by MCNP simulations taking into account the construction elements of the target module and cyclotron self-shielding. The contribution to the 99mTc yield by indirect production via 98Mo(n,γ)99Mo → 99mTc reactions was estimated.
