Scintillation Counting of Gamma-Rays

Nature, 1950
WE have investigated the significance of absolute counting-rate in the scintillation measurement of gamma-rays from radium-226, iodine-131, cobalt-60 and sodium-24.

Foggy scintillation counting technique

Applied Radiation and Isotopes, 2001
A new "foggy scintillator" was developed for the measurement of low-energy beta-emitters in air. By the use of an ultrasonic wave generator, a liquid scintillator can be converted into the "foggy scintillator". In order to obtain reasonable detection efficiency, it is necessary to prepare a liquid scintillator with a very high concentration of the ...

Fundamentals of scintillation counting

Seminars in Nuclear Medicine, 1973
The operation of a scintillator detector depends upon the detection of fluorescent radiation emitted from the phosphor following absorption of ionizing radiation. In organic phosphors this fluorescence takes place at the molecular level. In in-organic phosphors the fluorescence is dependant upon the crystal structure and impurities have to be present ...

A new scintillator for liquid scintillation counting

The International Journal of Applied Radiation and Isotopes, 1967
Abstract This report describes the results of investigations carried out with a new scintillator: 2-(4′-t-Butylphenyl)-5-(4″-biphenylyl)-1,3,4-oxdiazole (Butyl-PBD). Counting efficiencies and background counts of variously quenched toluene and dioxane systems containing Butyl-PBD have been compared with similar systems containing PPO and DM-POPOP as ...

Scintillation counting equipments

Journal of the Institution of Electrical Engineers, 1951
Two types of scintillation counter, employing the VX 5045 multiplier photocell and a phosphor, are described. The alpha scintillation counting equipment is a complete instrument for counting samples of low activity over an area of 10 cm2, at background rates of less than 2 counts per hour.

Chemiluminescence in liquid scintillation counting

Analytical Biochemistry, 1970
Abstract A new chemiluminescence reaction arising from the combination of trichloroacetic acid and bathophenanthroline during the liquid scintillation counting of the Fe 59 beta emission is described. This is compared to the previously reported chemiluminescence arising from a reaction between quarternary amines and peroxides.

Liquid scintillation counting at ambient temperature

Analytical Biochemistry, 1966
Abstract Ambient-temperature liquid scintillation counting of aqueous samples of up to 2 ml volume realized effciencies of over 80% for 14 C and 20% for 3 H in a dioxane-naphthalene scintillator. The use of external standardization for rapid determination of counting efficiency is presented together with some characteristics of a newly available ...
