[Noisebridge-discuss] Pristine, Retro Civil Defense Geiger Counters on eBay, 3 for $95

[Michael Kan Kan]

Radiation survey meters are not as sensitive as geiger counters.

 They sensitivity is " The ranges of this instrument are 0-0.5, 0-5, 0-50 and 0-500 roentgens/hour. They do not have a ticking sound like real geiger
counters.

 Indications on these instruments shows that you are too late

 The typical geiger counter ranges are in the sensitivity of 100 to a thousand times more sensitive.


 Do not confuse these unsensitive meters to real geiger counters.
