TL;DR: A 2 π large-volume liquid scintillation counter is used for measuring natural and tracer amounts of added radioactivity in people, animals and large samples as mentioned in this paper, which is mounted in a horizontal position and is shielded by 6 in. of steel.

TL;DR: A radioisotopic creaming rate was determined for each emulsion and can be used to compare microscopically identical emulsions and/or production samples of an emulsion to a previously determined standard.

TL;DR: The transmission of beta particles through calcium carbonate samples with different moisture contents was studied and it was found that the transmission was linearly related to the moisture content.
