Low level radioactivity measurements—limitations and new techniques London, July 1965

Abstract

This two-day symposium held at Imperial College of Science and Technology on 5–6 July 1965 was organized by a special working party, which included representatives of a number of societies and national organizations interested in the problems of radioactivity measurement. It is the first of a possible series of such meetings and a second symposium on liquid scintillation counting will be held at the National Physical Laboratory on 18–19 October 1966. Of two introductory papers one was an historical survey, concentrating on the physical features in the processes of detection and spectrometry of nuclear radiation, describing the individual experiments which led to the development of reliable Geiger counters, the proportional gas counter and the modern scintillation counter, and referring to recent developments in spark chambers for the identification of the actual paths of corpuscular radiations and the promise, especially in high resolution, offered by junction detectors.
