Geiger Counter 0,5 µS/h

This is an edit of a recording of a real Geiger-Müller-counter, detecting normal background radiation. The reading of the Geiger-Müller-Counter was averaging at around 0,13 µS/hour (read: "micro-sieverts per hour"). The recording was then cut into four equal-length parts and overlayed with itself, to create the sound the Geiger-Müller-counter would produce when reading 0,5 µS/h. This reading still would not be dangerous.

The recording was taken with two small-diaphragm condenser microphones in XY-configuration. The recorded signal was processed with a noise gate, to eliminate background hiss. No further processing was applied.
