Book Description
Alpha emitting nuclides frequently can be separated from one another and from interfering ions by solvent extraction procedures. If the last step of such a scheme automatically incorporates the nuclide of interest in a liquid scintillator (containing an extractant), a simple procedure for radioassay of the nuclide results. It is shovwn that correct choices of scintillators and detector systems produce further advantages. Quenching is minimized and held constant, so that the pulse height obtained from a given alpha energy is reproducible, and the energy resolution is improved over that obtainable with conventional liquid scintillation methods, so that alpha peak widths are decreased from around 1 MeV to 0.2 to 0.3 MeV at half maximum. Compatibility of several extractants with scintillator solutions is described. Procedures are described for separation and analysis of several nuclides (e.g., plutonium, uranium, and tnivalent actinides), including a specific application to the assay of plutonium in enviromnental samples.

Liquid Scintillation Alpha Spectrometry
Author: W. McDowell
Publisher: CRC Press
ISBN: 1351091034
Category : Science
Languages : en
Pages : 222
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.

Some Applications of Photon/Electron-Rejecting Alpha Liquid Scintillation (PERALS) Spectrometry to the Assay of Alpha Emitters
Author:

Languages : en
Pages :
Book Description
The combination of certain solvent extraction separations and a special kind of liquid scintillation detector and electronics designed for alpha spectrometry allows some highly accurate, yet simple determinations of alpha-emitting nuclides. Counting efficiency is 99.68% with backgrounds of 0.02 cpm. Energy resolution and peak position are sufficient for the identification of many nuclides. Rejection of interference from .beta. and .gamma. radiation is99.95%. The Photon/Electron Rejecting Alpha Liquid Scintillation (PERALS) equipment is described and procedures for the separation and determination of uranium, thorium, plutonium, polonium, radium, and trivalent actinides are outlined. 25 refs., 10 figs., 1 tab.
