The Detector

CAUTION: The mica surface of the Geiger tube is fragile. Be careful not to let
anything penetrate the screen.
Internal- For Inspector+ only
The Inspector+ uses a two-inch Geiger tube, commonly called a "pancake tube."
On the back of the Inspector+, the screen is called the window. See Figure 4. 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 (Figure 1 (7)) on the front label indicates the center of the Geiger tube .
External - For Inspector+ EXP only
The Inspector+ EXP has an external pancake probe instead of the built-in
