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 measured the construction of the self-absorption curves.

稀薄源喷涂法用于总的alpha / beta测量，重点是alpha / beta粒子的自吸收。

总体α/β分析是一种最初的快速筛选技术，用于区分核工业中的α和β粒子发射器。样品中的自吸收会影响检测。因此，必须建立自吸收曲线。在不同条件下绘制了Beta和α自吸收曲线。结果的重现性取决于铲刀上干残渣的均匀性。为了正确地确定和比较活性，样品的制备方法必须与测量自吸收曲线的方法相同。
