During the past year, new and improved radioisotope preparations were provided to medical research groups through cooperative programs for medical evaluation. The radioisotope preparations included ^69mZn, ⁴³K, ^92mNb, ³³P, ⁶⁷Cu, ^95mTc, and ¹²³I. The feasibility and economics of producing ¹⁷¹Tm as an isotopic power heat source for use in an artificial heart were investigated. The high neutron flux capabilities of the HFIR (used to study neutron production of radioisotopes) were determined in the beryllium reflector and the hydraulic tube positions. The thermal neutron cross section and resonance integral of 14°Ba were determined to be 1.57 ± 0.3 and 13.6 ± 1.4 barns, respectively, and the effective cross section of ²⁰⁴Tl was determined to be 23.1 barns. Thermal diffusion enrichment of the ⁸⁵Kr in the fission-product krypton provided 240 Ci of 13.97% ⁸⁵Kr and 370 Ci of 27.62% ⁸⁵Kr. Field tests with ¹³³Xe-tagged sand were carried out at three locations to evaluate equipment and to develop more effective procedures for use in studying the direction, the velocity, and the volume of sand movement.
