闪烁体探测器具有探测效率高和灵敏体积大等优点,其能量分辨率虽然不如半导体探测器好,但对环境的适应性较强,在环境本底下灵敏度高。有机闪烁体如塑料闪烁体性能稳定,不易潮解,机械强度高,易于加工成各种形状,且抗辐照性能是目前各种闪烁体中最好的,可用于高剂量、强辐射剂量率的辐射场。无机闪烁体如NaI晶体虽易于潮解,但一般用铝材料和有机玻璃封装后便可使用,其灵敏度比塑料闪烁体高,加上后续的多道技术可用于测量γ射线的能谱。因此,闪烁体仍是广泛使用的核辐射探测器。其中信号处理电路的设计直接影响到测量仪表的性能,是仪表设计的 Scintillation detector has the advantages of high detection efficiency and large sensitive volume. Although its energy resolution is not as good as the semiconductor detector, its adaptability to the environment is strong and its sensitivity is high under the environmental background. Organic scintillators such as plastic scintillators have stable properties, are not deliquescent easily, have high mechanical strength and are easy to be processed into various shapes, and the anti-radiation performance is the best of all kinds of scintillators and can be used for high dose and strong radiation dose rate Radiation field. Inorganic scintillators, such as NaI crystals, tend to deliquesce, but they are usually packaged with aluminum and organic glass. Their sensitivity is higher than that of plastic scintillators, and the subsequent multi-channel technique can be used to measure the energy spectrum of gamma rays. Therefore, scintillators are still the most widely used nuclear radiation detectors. Which signal processing circuit design directly affects the performance of measuring instruments, instrument design
