A closeup view of the Professor's simple Geiger counter.
Bio==
The principle behind a Geiger counter is that a tube filled with an inert gas is charged electrically allowing for the detection of radition by sensors. Very little is known of the Professor's implementation. No tubes or electrical source is seen, but a measuring scale can be seen on the face of his counter.
