We are selling our house, and the buyers are having a radon test done. I didn't know much about radon tests, so I looked it up on the Internet. The part that I have questions about is how the actual test is done. Everything I have read so far said to place the test 20 or more inches off the floor, and at least 2 feet away from exterior walls. Guess where the test is located in my house? Yep, on the floor, about a foot away from the wall. Also, the test vials look to be capped? Anyone know anything about this?
How would the results be affected if the test box is sitting on the floor so close to an exterior wall? That is assuming that the test is actually in progress. Thanks in advance.
It will not really matter to the results if placed on the floor. I have done thousands of radon tests with continuous monitors in every type of variance you can imagine. What part of the triangle are you in?
I am not sure about caps on the vials as we use monitoring equipment and never had experience with the send-off style tests.
The only test we have had done were with monitoring equipment and not vials for lab testing. Either way, don't worry about the means of testing unless it comes back high and you HAVE to worry about it. I understand where you are coming from but don't worry about how the radon levels were measured unless the radon levels were a problem.
All that said, I doubt any court or company would say that it mattered that the equipment was stationed on the floor.
it will give you all the information you need to know.
we recently bough a home and radon test showed very high radon reading. the seller paid almost $2000 to install a fan in the crawl space which brought the levels below the permissible exposure limits.
since you are selling a home, you will have to fix it if the level is high. check your contract with the buyer and see what it says. most of time sellers fix this problem otherwise buyer just walks away. i am not trying to scare you but you can keep this possible expense in mind.
as far as location of test is concerned, the radon guy will place it but you have to make sure that it is not disturbed.
I think a continuous monitoring device is the best. The inspector can tell if it hs been tampered with or not, or if windows were left open etc.... Not al inspectors use this because it is very expensive. The inspector I use does use this device. Here is a picture of one for you.

Radon gas is heavier than air and has a higher concentration at floor level......thats why they recommend testing be done at least 20" off the floor !!!!

That is the official recommendation, but it really does not have any effect on the end result (mainly due to the air not being stagnant in a house). I have tested my house over the years in the crawlspace, on my granite counters, at floor level, on a stool, and up high on shelf.... readings all within a tenth.

Then I would tell you that you need a refresher course in radon testing.......placing test equipment on the floor would be considered an invalid test, at least in New Jersey.........call it recommendation or protocol.......if the protocol isn't followed its invalid. Finally, I will state again.......radon gas is heavier than air thats why the highest readings are in the basement and test euipment should be placed in whats known as the "breathing zone". Equipment on the floor is clearly not in the breathing zone unless you spend a lot of time unconscious and laying on the floor. Whats the use of having an EPA testing "recommendation" or protocol if your going to ignor those recommendations make up your own testing proceedures as you go along ??? No wonder many agents and home owners are skeptical of the radon industry if you can't follow the set rules.
