For short-term radon measurements with exposure times between 48 hours and 96 hours, we utilize the liquid scintillation (LS) type of patented pharmaceutical-grade charcoal-silica adsorption material. Near 100% counting efficiencies allow for a monitor that is lighter in weight (0.4 ounce) and easier to handle than traditional charcoal canisters. High efficiency counting also means that fewer samples are lost due to excessive decay time.

Each detector is given a unique bar-coded identification number. A measurement with the LS device in initiated by removing the cap to allow radon-laden air to diffuse into the charcoal packet where the radon is adsorbed. A polyethylene foam plug ensures passive diffusion, preventing distortions caused by drafts and air currents. At the end of the exposure (two days), the device is resealed securely and returned to our lab for analysis.

In the laboratory, the exposed detectors are prepared for analysis by radon desorption techniques. A major fraction of the radon adsorbed on the carbon is transferred into a vial of liquid scintillation fluid. The vials of counting fluid are then loaded into an automated liquid scintillation counter. The total beta activity is then counted for a pre-set time or until the standard deviation of the counts is at 2.5%.

The total beta count, along with the customer supplied exposure data, is used to calculate the radon concentration. The typical uncertainty (standard deviation) of an LS result is ±10% and the minimum reported concentration is 0.5 pCi/l.

We heard about your company on our local news channel. They did a story on radon gas in our community and state. As part of their story they used 6 radon test kit suppliers to test a multitude of buildings. Your company impressed them the most with your good prices and prompt report. So we agreed to try our first online experience with you and it was smooth. Our house tested safe, but 2 of our neighbors had high levels. All of us had a good experience with your company. Thanks! We will be doing business with you again! Rob & Chloe

I used your test kit with conjunction with other monitor. PC and, geiger counter with filter to detect Radon children components. The PC unit with filter ON indicates ~ 7MicroR/Hr = 1PC/Liter. Based on experience. It indicated 12MicroR/Hr above base ~ 1.714 PC/Liter. Your test result was 1.7PC/Liter. Both results are very close. Thanks.

Your prompt service is much appreciated. I have other labs who have asked me to switch to their service. I am obliged to inform them that you are the man. Steve Sears - Liberty Home Insp.

My neighbor had their house tested for $125 by a radon company. By the time they got the radon lowered with all of the tests they spent over $2000. We discovered that the radon contractor used your labratory so we got our kit for about $20. When we discovered we had high levels we decided to get the electronic detector you have. (Pro Series). With the detector, the initial test & supplies to lower the levels we spent about $625. By the way, our levels were higher than my neighbor's. Your site helped a lot.

My class performed tests as a project. Best educational project we involved them with so far. We will be doing this with each class from now on & using your products / laboratory services.

All I can say is the reading I got from your test ($20) was the same as my home inspector's ($135). I am ordering some for our association so we can do spot checks in our community.
