An automated, highly reproducible fast-transfer system (0.36±0.01 sec) has been developed, an oscillator/multichannel-scaling
system has been developed to follow rapidly-changing spectrometer dead-times, the mathematics has been developed, and the
data processing steps have been computerized. Three induced activities have been studied in some detail:207mPb (0.80 sec),38mCl (0.70 sec) and20F (11.03 sec). Both steady-state and high-intensity pulsed reactor irradiations, with and without a Cd liner, have been used.
The dead-time correction method has been carefully checked, and the overall method has been tested by the analysis of two
NBS Standard Reference Materials: orchard leaves (for Cl and Pb) and bovine liver (for Cl).
