Every once in awhile I get a call regarding proper test placement. I do have protocols on the web site explaining the protocols. I had forgotten that we did a few experiments earlier this year with test placements. One in Particular really showed why it is so important to place the test properly. A Radon test needs to be a minimum of 20 inches above the floor, as part of the test set up. There are other items to adhere to also, but I just want to cover the height with this post. I am going to paste a test printout that shows results as the monitor sat on a stool, which was about 24 inches above the floor, and then was moved and placed onto a carpeted floor. Now in this test they would have probably still test high. But what if they were in the 1-3 Pico curie range? Having the test on the floor would have greatly skewed the results. When it comes to Radon testing, make 100% sure that the test is being placed properly.
