Description

Organic Scintillation and Liquid Scintillation Counting covers the proceeding of The International Conference on Organic Scintillators and Liquid Scintillation Counting, which was held on July 7-10, 1970 at the University of California, San Francisco. This conference was held to discuss ideas concerned with the theory and physics of organic scintillators and the use of liquid scintillation for radioactivity measurement and other analytical applications.

This text discusses liquid scintillator solvents, the vacuum ultraviolet excited luminescence of organic systems, and the application of scintillation counters to the assay of bioluminescence. Also covered are topics such as scintillation decay and absolute efficiencies in organic liquid scintillators, dose rate saturation in plastic scintillators, and the mass measurements in a liquid scintillation spectrometer.

The book is recommended for physicists who would like to know more about the advancements in the field of organic and liquid scintillation and its applications.
