Transistor Counting Systems for Scintillation Detectors [PDF]

IRE Transactions on Nuclear Science, 1960
The requirements for multiple-coincidence counting systems with 10-8 to 10-9. sec time resolution can be met economically with presently available high-frequency transistors. The design of solid-state coincidence circuits, amplitude discriminators, and decade scalers is considered and their operation discussed.

Influence of natural radium contamination of barium chloride on the determination of radium isotopes in the water samples using α/β liquid scintillation spectrometry

Nukleonika, 2016
The determination of radium isotopes in drinking water by liquid scintillation technique requires some reagents that are used for separating radium from water samples. One of the main reagents is BaCl2·H2O.

Improved methods for the assay and activation of 3-hydroxy-3-methylglutaryl coenzyme A reductase.

Journal of Lipid Research, 1979
A simple and rapid mixed-phase method for the quantitative assay of 3-hydroxy-3-methylglutaryl (HMG)-CoA reductase and a procedure for the efficient reactivation of Mg-ATP-inactivated microsomal HMG-CoA reductase by potato acid phosphatase are described.
