Pagination or Media Count:
Thermal neutron activation of 99Tc to 100Tc by the n, gamma reaction was used to determine picogram amounts of 99Tc in a highly purified aqueous medium. A rapid post-irradiation procedure was developed to purify and separate 100Tc fraction from other induced radionuclides in 40-45 seconds. The technetium yield of 53 plus or minus 5 was conducted in a low background beta-counter. Author
