固体径迹探测器广泛应用于科学和技术方面,CR39是其中使用很频繁的一种塑料探测器。由于电子和伽马光子在CR39中的碰撞截面很小,远小于中子、质子或其他离子的碰撞截面,因此可
Solid track detectors are widely used in science and technology, CR39 is one of the most frequently used plastic detectors. Due to the small cross-section of electrons and gamma photons in the CR39, which is much smaller than the collision cross-section of neutrons, protons or other ions,
