349.5 CPM (counts per minute) = 3495 over the course of 10 minutes. (first test was 250+ CPM over 5 min - not on camera -- several more tests over the next few days forthcoming) By all accounts, 100 CPM is the alert level for "high radiation". This means we are far over alert levels when it comes to small radioactive particulate matter in the air. This boldly contradicts my previous findings from cross country measurements.. highest levels cross country were in Colorado @ 80-100 CPM location : Saint Louis, Missouri date : 11/18/2011 1200 noon CST Method of collection: electromagnetically charged particle collection plate 30 minute collection (stainless steel) -- ionic breeze air purifier collection plate steel plate wiped with a fresh dry paper towel.. then placed on a clean glass surface. Geiger counter is the "inspector alert" medcom.com Both paper towel and plate pre-tested for ambient background radioactivity (normal) on video. I intend to repeat this test several more times as well as tomorrow (nov 19 2011) taking several outdoor measurements across the Saint Louis Missouri area using the same collection method. It appears that regular geiger counters are NOT picking up even LARGE amounts of particulate radioactive material.. (not talking about hot particles here but particles of actual debris material in the air) it requires a collection apparatus which then allows one to be able to measure a "stationary sample" of the particles--- this is done when the particles ...
