HEPA PART 1
THE NUMBERS & ANALYSIS
2:15 pm 10-minute INTERIOR average of HONEYWELL HEPA FILTER HOT SPOT FROM 7/19/11 = 23 DAYS OF USE IN RADIATION STATION: 85 CPM which is 237% of PREVIOUS INTERIOR BACKGROUND OF 35.8 CPM
When the Honeywell HEPA filter air cleaner’s Pre-Filter light came on, it was time to vacuum out the barrel-shaped device and test the contents. Even without any rain and just 23 days of service since the last cleaning and testing, one spot on the pre-filter, as this video shows, came in approximately 85 CPM in this spot check, much like the one done on those two peaches 208% of background that caused quite a reaction. Unlike those peaches, which you can choose to consume or not, the air is something you must breathe. And even here in sunny Southern California, south of the jet stream that is transporting fallout across the U.S., Canada and beyond, this filter saved our lungs from inhaling fissile radionuclides, an important reduction in our overall radiation burden reduction efforts.
HEPA PART 2
THE NUMBERS & ANALYSIS
3:00 pm 10-minute INTERIOR average of HONEYWELL HEPA FILTER AGGREGATE FROM 7/19/11 = 23 DAYS OF USE IN RADIATION STATION: 80.0 CPM which is 229% of PREVIOUS INTERIOR BACKGROUND OF 35.8 CPM
Radiation Station is generally upwind of most of the Greater Los Angeles Basin and close to the Pacific Ocean. Even with the sea breezes, the dust you see collected and compressed from the Honeywell HEPA machine is substantial, especially considering that the station is dusted and vacuumed regularly. By vacuuming out the HEPA machines, they return to higher flow rate efficiency and the aggregate dust and debris can be analyzed. The ten-minute average gives a much more credible number than spot checking. That said, the close values of the aggregate average and the hot spot checking indicate accurate spot checking technique.
The high 237% of previous background reading indicates that even without rain, fallout is still impacting our area brought in, in part, by our season “June Gloom” which we have found to have had elevated radiation readings. We reduce how much radioactivity we track into Radiation Station by removing our footwear and keeping the floors squeaky clean.
HEPA PART 3
THE NUMBERS & ANALYSIS
3:50 pm 10-minute INTERIOR average of KENMORE PLASMAWAVE AIR CLEANER/HEPA FILTER AGGREGATE FROM 7/19/11 = 23 DAYS OF USE IN RADIATION STATION: 68.1 CPM which is 190% of PREVIOUS INTERIOR BACKGROUND OF 35.8 CPM
Reducing and eliminating exposure to radioactivity in the air and dust is enhanced by use of HEPA filters in the home and office. Even with a heavy duty ionizer in a second room of Radiation Station, the Kenmore Plasmawave machine still picked up 190% of background, significant relatively dry weather Southern California has been experiencing. Other HEPA filter readings in the region, including nearby Glendale, also show heightened ionization.
Fukushima Daiichi fallout is not run of the mill ‘natural’ radioactivity like the uranium and radium found in many soils. It is made up of five months’ worth of three nuclear reactors melting down and spewing astronomical amounts of radiation into the atmosphere and Pacific Ocean. The jaw-dropping recent rain readings in Oklahoma City, North Carolina, western and central Canada do not evaporate with the rain. They remain and are effecting our water supplies, crops, livestock and this continent’s wildlife forced to feed and drink upon this disaster’s fallout.
These videos show that even out of the hottest zones (and that’s not even including Japan, wide swaths of which are massively irradiated), significant radiation is being found in sunny Southern California in the mists and air.
@Concerned Citizen: Possibly. What is the background reading? ~50 CPM (Counts Per Minute) would be a high-ish background for Southern California which is higher than many places. Therefore, your reading is 10 times that, significantly more than the 3 times background that the California Highway Patrol considers the trip-level for a Hazardous Materials scenario. Careful dumping that dust!
Is 500 cpm on an air filter prefilter measured with a radiation alert ranger bad?
I just moved to Iowa from Santa Barbara for a few months. I’m wondering about the fall harvest and the fall out. Any data out here???
its a damn shame. im 19 years old and live in lakewood and im trying to convince my dad into investing in these products but he keeps telling me im a hypochondriac. i will up and leave to go as far south east as possible
We are all [screwed].
There is no doubt that the HEPA filters are sweeping up airborne radiation and helping to protect Michael and Denise from inhaling radioactive particles. I’m surprised that the counts are 2X background after only 23 days. With no rain to wash the fallout from the sky to ground level, and the jet stream normally traveling much farther north over the Pacific Northwest, I didn’t expect to see so much in the Santa Monica area. Well, I’m keeping my HEPA filters running here in Glendale, CA, too. It seems to be a very prudent precaution.
