The Detector
CAUTION:
The mica surface of the Geiger tube is fragile and should be handled with care. Be careful not to let
anything penetrate the screen.
The Inspector uses a two-inch, thin window Geiger tube, commonly called a “pancake tube.” The screen on
the back of the Inspector is called the window
Figure 4 (1)
. It allows alpha and low-energy beta and gamma
radiation, which cannot get through the plastic case, to penetrate the mica
surface of the tube. The small radiation symbol on the front label indicates the
center of the Geiger tube
