Efficiency of 4p-crystal-scintillation counting: 1. Experimental technique and results

Efficiency of 47T-Crystal-Scintillation Counting: 1. Experimental Technique and Results

The technique of 47r-crystal-scintillation counting has been applied to the s tandardization of beta-emit t ing nuclides. Phototubes viewing an anthracene sandwiched source a t 180° have been used with high-gain nonoverloading amplifiers in addition and in coincidence circuits to obtain high detection efficiencies. A precise shorted delay-line coincidence analyzer is described. The results of m...

Determination of accurate counting efficiency for liquid scintillation counting.

Luminescence and scintillation characterization of Silver doped KCl single crystal grown by Czochralski technique for photonic applications

In this study, the scintillation and optical properties of pure and silver doped potassium chloride (KCl:Ag) single crystals were reported. Pure and doped KCl bulk single crystals with a good optical quality and free from cracks were grown from the melt using Czochralski technique. Different analysis methods were used to study the optical and scintillation properties of the grown crystals. The ...

Liquid Scintillation Counting

discussed, and he points out that merely because a disease is found to be familial in incidence does not mean it is hereditarily transmitted; leprosy, for instance, was long held to be a hereditary disease, and a law was actually proposed in the Norwegian Parliament forbidding the marriage of lepers for that reason. It was only with the discovery of the leprosy bacillus by Hansen that the true ...

Cocktails for Liquid Scintillation Counting

It is most important to assure 4 π−geometry in liquid scintillation counting for accurate results1. Usually this can be assured by dissolution of the sample in an appropriate cocktail. The cocktail does not only contain a solvent but also at least one scintillator and surfactants for aqueous samples because aqueous samples are completely insoluble in the pure organic solvents and scintillators....
