液体闪烁测量方法是近二十几年出现的一种测量软β射线的新技术,具有灵敏度高、测量时间短、制样方便、便于重复测量、耗样少等优点。自1973年国产 FJ——353型双道液体闪烁计数器正式生产以来,大大推动了国内液体闪烁测量法的应用与发展。它对软β射线的测量充分显示出高灵敏度和高效率的优点,在各方面已获得了广泛
Liquid scintillation measuring method is a new technique to measure soft β-ray in recent twenty years. It has the advantages of high sensitivity, short measuring time, convenient sample preparation, easy repeated measurement and less consumption. Since the formal production of FJ - 353 dual - channel liquid scintillation counter made in China in 1973, the application and development of liquid scintillation measuring method in our country have been greatly promoted. It has fully demonstrated the advantages of high sensitivity and high efficiency in the measurement of soft β-rays and has gained wide acceptance in all aspects
