Production of 177Lu by neutron activation of 176Lu

  • Y. Nir-El


Production of the radiopharmaceutical nuclide 177Lu, by direct thermal neutron activation of 176Lu, poses a discrepancy between experimentally measured and theoretically predicted activities. It was found that in the irradiation at the pneumatic transfer tube (‘Rabbit’) of the IRR-1 reactor, the exper./theor. ratio was 1.858± 0.051. This ratio was determined also by comparing the activities of 177Lu and 176mLu. The significant deviation of 176Lu from the 1/v behavior explained this disagreement. The ratio exper./theor. is the Westcott g(Tn)-factor and was used to yield the neutron temperature Tn = 311±8 K.
