Gross alpha/beta analysis is an initial rapid screening technique used to discriminate alpha- and beta-particle emitters in the nuclear industry. Self-absorption in the sample affects the detection; therefore, self-absorption curves must be constructed. Beta and alpha self-absorption curves were constructed under different conditions. Results reproducibility depends on uniformity of the dry residue on planchets. To determine and compare activities correctly, the preparation method of the sample must be identical to the ones mea
