Assembly of a low level beta radiation measurement system

Beta radiation detection systems are used in different fields, such as: environment, industry, medicine and radiation protection. In this study, a measurement system using a 3 mm plastic scintillator was assembled. This detector dimension provides and efficient detection for beta radiation and practically no interference from the laboratory background radiation. A limitation for the environmental measurement application is the high rate of background radiation. With the use of an anti-coincidence system a background of at the most 2 counts per second was obtained. (author)
