  • What's wrong with the Rn system they ask.
    It is a homeowner DIY system. That grey thing is a central air unit.

    John Reim: Not being the owner of the company, I can only advise, not demand. We do run about a 50/50 split between 1027/1028. However, when you're the largest measurement company in Nebraska, with almost 50 monitors, replacement is anything but inexpensive. As for "radon professionals" in quotes, Nebraska is a licensing required state through the state's Department of Health and Human Services.

    I came to the same conclusion, that the homeowner interrupted the power 3 hours into the test. Then, at some point, reintroduced power. I did nullify the test and required retesting with strong words to the homeowner. By the time I was done he was thinking that monitor could see and hear everything going on in the entire house. Unfortunately I work for does not require the homeowner to sign a non-interference agreement.
    Upon retesting, the retest resulted in an EPA overall average of 4.6, lower than the 7.1 on the first test, so I'm not so sure the homeowner followed closed house conditions during the second test. However, in any case, that house is on it's way to mitigation.

    Test results from a 1027 test. Test was set on a Friday and picked up on Monday. House was occupied, homeowner states that the monitor was plugged into a power strip that was turned off at the time of set and when they noticed it, they turned it on.

    ------------------------






    EPA recommends that readings of 4.0 pCi/L

    or higher have actions taken to reduce the

    levels of radon in the home.



    Interpreting the results / graph attached: The

    boxes/sets of numbers represent the presence of

    radon…the more boxes/higher numbers in the sets,

    the higher the concentrations for that hour.


    The "T" indicates that during this measurement

    interval the monitor was disturbed, touched,

    or moved. The "P" indicates that during this

    measurement interval, the power was lost or

    disconnected from the monitor.
