在低本底α放射性测量中,金硅面垒半导体探测器、电离室、正比计数器和硫化锌闪烁探测器等都被广泛使用。它们各有其优缺点,但由于ZnS(Ag)闪烁体的材料便宜,制备工艺简单,因此使用得更广泛。 在低水平α放射性测量中,由于α粒子的电离密度大,能量高(一般大于4MeV),因此α粒子在探测器中产生的脉冲幅度比β粒子、μ介子大得多,测量装置不需要笨重的物质
In low background α-radioactivity measurements, gold-silicon surface barrier semiconductor detectors, ionization chambers, proportional counters, and zinc sulfide scintillation detectors are widely used. They each have their own advantages and disadvantages, but they are more widely used due to the cheap material and the simple preparation process of ZnS (Ag) scintillators. In low-level alpha radioactivity measurements, alpha particles have a much larger pulse amplitude than beta particles and muons in the detector due to their large ionization density and energy (typically greater than 4 MeV), and the measurement device does not require bulky Material
