Victoreen VAMP 808 B Radiation Monitor

The Victoreen VAMP was used in environments where constant monstering was necessary. Rad labs, hospitals and factories are just some of the places where these were and possibly still used. Could be mounted to a wall and if a preset threshold was met an alarm would sound. I don't know if this one is normal because I haven't seen another in operation but it sure sounds like some kind of code when the alarm goes off. It actually scared me the first time I set it off.
