Abstract:

Half-lives of thermal neutron activated samples were determined by direct decay measurements. Transport of samples between activation and counting areas was accomplished by employment of a rapid pneumatic transfer system. Use of a single channel analyser with a fast chart recorder to record scaled counts vs. time, and analysis of these data in a computer program are discussed.
