Detection of radiation in environmental samples is commonly conducted in liquid scintillation counters. Both commercial-off-the-shelf detectors and custom-built ultralow background counters are limited by the radiopurity of the liquid scintillation cocktails themselves, most specifically from 40K, an environmental radioisotope of potassium. Major radioactive contaminants are 40K, 232Th and 238U (and their decay chain progeny). 40K is a naturally occurring radioisotope in the environment and can interfere with the sensitivity of analytical instruments. The invention provides a method for purification and removal of potassium (40K) from liquid scintillation cocktails. nonpolar and surfactant solutions and mixtures, thereby reducing the abundance of 40K from the scintillating cocktail and improving sensitivity of analytical instruments.
