由美国Crawford等设计的一种100MNz射频辐射暴露装置,适于大鼠等动物做实验,以便观察超短波的生物效应。该装置还适用于标定宽频辐射监测仪。 该装置主要由横向传播电磁波(TEM型波)的长方形横断面的同轴传输线组成(Crawford小室)。此装置一次能暴露20只大鼠,将它们等量地分放在传输线中央导体的两侧,放置动物的暴露区域 Designed by the United States Crawford, a 100MNz radio frequency radiation exposure device designed for experiments in rats and other animals in order to observe the biological effects of ultrashortwave. The device is also suitable for calibration of broadband radiation monitors. The device consists mainly of coaxial transmission lines with rectangular cross-sections of transversely propagating electromagnetic waves (TEM waves) (Crawford cells). This device can expose 20 rats at a time, divide them equally on both sides of the center conductor of the transmission line, place the animal’s exposed area
