Abstract
Samples of 24Na, 42K, 76As and 198Au were produced by irradiation in the National Institute of Standards and Technology (NIST) reactor, and examined for impurities before and after measurement. Half-life measurements were carried out in the NIST 4pigamma pressurized ionization chamber. The results are compared to presently accepted values and previous NIST measurements.
