Liquid Scintillation Alpha Spectrometry


Book Description

Alpha liquid scintillation was developed to obtain accurate analytical determinations of alpha-emitting nuclides where no other methods were sufficiently accurate. With the present emphasis on clean-up of radiation contamination, alpha liquid scintillation has become an important tool in the determination of low concentrations of alpha-emitting nuclides. This book is the first to address the subject of alpha liquid scintillation in its entirety. It also examines how alpha spectrometry by liquid scintillation can be done without interference from beta/gamma radiation. Scientists interested in the analysis of alpha-emitting nuclides for environmental monitoring, remediation clean-up, accountability, and research will find this to be a valuable book.




Liquid Scintillation


Book Description

Liquid Scintillation: Science and Technology contains the proceedings of the International Conference on Liquid Scintillation: Science and Technology held on June 14-17, 1976 at the Banff Centre in Alberta, Canada. The book presents papers on the mechanisms of the liquid scintillation process; liquid scintillation alpha counting and spectrometry and its application to bone and tissue samples; and measurement by liquid scintillator of labelled compounds (3H or 14C) dropped onto supports. The text also includes papers on the heterogeneous counting on filter support media; liquid scintillation in medical diagnosis; and the theory and application of Cerenkov counting. The radioassay of chlorine using a liquid scintillation spectrometer; some factors influencing external standardization; and the study of the sizes and distributions of colloidal water in water-emulsifier-toluene systems are also considered. The book further tackles the external standard method of quench correction; the liquid scintillation counting of novel radionuclides; and Cerenkov counting and liquid scintillation counting for the determination of fluorine. The text also looks into the absolute disintegration rate determination of beta-emitting radionuclides by the pulse height shift-extrapolation method; automatic data processing in scintillation counting; and the standardization in liquid scintillation counting. Biochemists and scientists involved in the study of chemical biodynamics will find the book invaluable.

An Alternating Sample Changer and an Automatic Sample Changer for Liquid Scintillation Counting of Alpha-emitting Materials


Book Description

Two sample changers are described that were designed for liquid scintillation counting of alpha-emitting samples prepared using solvent-extraction chemistry. One operates manually but changes samples without exposing the photomultiplier tube to light, allowing the high voltage to remain on for improved stability. The other is capable of automatically counting up to 39 samples. An electronic control for the automatic sample changer is also described.
