I had some down time with a couple of my radon monitors, and decided to do some experimenting.
I placed two Sun Nuclear 1027’s right next to each other in my office. One I placed a salad bowl over to “cover” it, and the other I left exposed. Left them there.
Here is the result. They are virtually identical. The uncovered one was 0.6, the covered one was 0.7.
I was expecting something more on the lines of a flat line on the covered one. I may re-run this again sometime, but seal the bottom of the bowl with plumbers putty.
In this case, covering the monitor did absolutely nothing to alter the results because the thickness of the cord, “propped” the edge of the bowl up enough that secular equilibrium was established through that crack.
That tells me that even if a home owner tried to do this too, it wouldn’t make any difference.
What do you think?
