Four specific types of censoring were found in the EPA data:
(1) Censored Data (deletions): Specifically Gross Beta, and Gama Energy Ranges 2 through 5, and 7.
(2) Censored Data (Burn-offs): Short Half life radiation was allow to burn-off from the sample by performing the sampling in time frames longer than the standard 1 hour sample collection time.
(3) Censored Data (short sampled): Sampling periods were cut short of their standard 1 hour sample gathering time; the result is a radiation count that is proportionally lower.
(4) Censored Data (early filter removal): Filters build up radioactive contamination. By installing a new air filter before the previous filter's useful life span has been reached, the subsequently recorded radioactivity will appear lower.
Based on my understanding of the RadNet's operational guidelines:
Samples are automatically captured every hour and sent up to the EPA to "review" the data before it is posted online. The air sampling cartridges are to be removed every 12,000 cubic meters and sent to the EPA for further analysis; this time may be cut short if unusual radiation detections are found.
As I searched through the EPA RadNet data for Saint Louis, I found two instances where a new air sampling cartridge was inserted and removed with in one or two readings and replaced with another new cartridge. The first such occurrence was on April 10th and was concurrent with all four types of observed censorship. The second occurrence was on May 25th and was concurrent with a large radiation increase.
The EPA website does state that "Electrical interference can cause spikes, shown on graphs as one point significantly higher than the rest of the data". However an examination of the data found NO such instantaneous spikes, only radiation increases predicted via previous upwards trends.
It is also interesting to note that the heaviest data censorship occurred in the early parts of the Fukushima disaster, where radiation levels would have been expected to be at their initial highest. Despite that heavy early point data censorship, the overall trending data from March through May shows a significant increase in radioactivity. I believe the increase is significant from a cancer causing perspective, but not necessarily from the perspective of inducing Radiation Sickness.
Hopefully the EPA will provide an alternate explanation of the above analysis and will support such an explanation by:
(1) Releasing all the RAW un-manipulated data
(2) Releasing all manuals and instructions covering the collection of such data.

Very well done, Sir. Any chance you might want to down load the Kauai data into your spreadsheet and see what it shows?
ReplyDeleteI can't promise it will be quick, but I'll take a look at it
ReplyDeleteCool thanks. I think it might be interesting as Kauai has had some radiation spikes on www.radiationnetwork.com Here is one of a number of articles on it http://hawaiinewsdaily.com/2011/06/kauai-radiation-monitors-detect-possible-fukushima-fallout/

ReplyDeleteI tired to figure out the RadNet down load. Couldn't get it. Hoping you will, for Kauai data, when you have time.
ReplyDeleteEPA obfuscated the links and are calling them closed
ReplyDeleteYou can still find the Kauai data here
http://www.epa.gov/japan2011/rert/radnet-kauai-exp-rate.html
the data can be down loaded here
https://cdxnode64.epa.gov/radnet-public/query.do
select "Deployable Monitor List"; select all the parameters; and then select "Deployable Monitor ID" RN20.
The data is in a simpler format; it should be easier to analyze (just look for time blocks where they did not take data). But there is a HUGE amount of data and I won't have time to down load it all for at least a couple of weeks. If you can take the time to do the down load, the analysis won't be that difficult.
I did take a quick look at the Honolulu data, and it is in the same format as the Saint Louis data; I noticed they deleted gamma energy range 5 on April 26. But again, I wont have time to go through it in detail for a couple of weeks.
