UPDATE:

This is still working after four years. I just changed the battery, and I can’t remember the last time I did that. This Radon monitor just works for months at a time!

We ordered a couple of “sample and mail” radon kits for Radon surveillance from a highly recommended company with an excellent reputation. . This battery powered Radon detector was placed in the same general area at the same time as samples were collected for lab processing.

When the commercial lab results came back, we were pleased to see that the results from this electronic Radon detector were comparable, and provided a continuous 24×7 monitoring solution.

It is small, and is placed on a wall at eye level in an area that is not exposed to drafts. The batteries last for months and the light weight allows it to be placed almost anywhere with only a small picture frame tack.
