Radiation Detected!

3/28/2011 - Testing For the Plume, Yukon, OK Statistics 101 No Radiation

Well, here are today's results, in graph form and raw numbers:

 

After working on this for some time a bit of statistical analysis really needs to be applied to my numbers.  Admittedly, I was a bit over excited about what I had seen on Saturday, and like many people jumped to an improper conclusion about what I was seeing.  My original hypothesis was that if the window swipe count was higher, then "bingo" the smoking gun, or in this case fission products from Japan!  However, the more I learn about statistics the Swipe count from Saturday was simply a statistical anomaly.  This is where it gets a bit complicated.  The first day I used a dirty window, so I will remove that test from the bunch.  This leaves me 11 days of testing, so just using the swipe test the average it is 12.3 CPM.  Now a bit of statistics needs to be applied (the Poisson Method), so adding together all the counts (remember, 5 minute count average) is 677.  If I take the Square Root, 26.0192236625 and divide by 5 I get the sigma, or in other words, I need to see 5.2 counts per minute average more to have anything that is statistically significant and indicates "yes" the plume is detectable with the equipment I have.

Obviously, that puts a damper on my Saturday "discovery".  So now what am I testing for?   The EPA says that what they have found is a very small amount, if I detect it then I will know without a doubt that there is a greater amount of radioactive contamination, since I am not using as high tech equipment as they are.  They are using continuous filtration of air and very high dollar germanium detectors (I saw one on eBay once, $10,000!).  Also they need to be cooled with liquid nitrogen.  So even operating one is expensive.  At least now I know what I am looking for.  However, even if I do get the expected count, that doesn't necessarily mean that the radiation is coming from contamination from Japan.

No, not exactly. They do make raaidtion capsules that can be implanted in the cancerous area to help fight the cancer. Usually used in persons with stage 2, 3 and 4 cancers.But there are no raaidtion pills that you can take orally. Radiation HAS to be in the affected areas only.
