Popis:	A new approach employing cancellation technique for reducing background of G.M. counter (size: diameter = 2.5 cm, length = 5 cm) to less than 2 counts per minute has been developed for the measurement of low level beta activity of the order of 25 micromicrocuries. The method and electronics used for cancellation are described. This method is a simple alternative to the usual anticoincidence shielding and needs only two G.M. counters for determination of moderately low level beta activities. This technique has been successfully applied for the study of the activity of biological samples from sea.
