Measuring Radioactive Methane with the Liquid Scintillation Counter [PDF]

open access: yesApplied and Environmental Microbiology, 1979
Although a gas proportional counter is the most convenient method of measuring the radioactivity of fixed gases such as methane, it cannot be used when high nonradioactive concentrations of methane are present in the gas phase, due to quenching. If only methane and carbon dioxide are present in radioactive form in the gas phase, a liquid scintillation ...
