Our last HEPA filter measurements January 22 produced some astonishing results. Doing a spot test on the Honeywell barrel-style filter and a Kenmore Plasmawave machine, we found radiation ~351% of normal background. The machines had been running for 42 days. The combined aggregate dust came in even hotter at 538% of normal background radiation at Radiation Station Santa Monica.
The California Highway Patrol considers anything over three times background, 300% of background and above, a trigger level to a hazardous materials situation.
