How is Radon Measured?

You had a radon test done. It came back “high” at 5.0 pCi/L. What? What does that mean? That doesn’t exactly seem high. How is radon measured? Radon is measured in “pico-Curies per liter of air” abbreviated as pCi/L. The radon measurement gets its name from Madame Curie.

How is radon measured?

A single pCi/L is the equivalent to 2.2 radioactive explosions every minute within every liter of air. Again – what on earth does that mean? Think of a 1,000 square foot box. It’s 100 ft by 10 ft by 10 ft giving you a cubic volume of 10,000 ft. 10,000 cubic feet is about 283,168 liters. If this 1,000 square foot home had just 1 pCi/L it would mean that there are 622,969 explosions happening every minute of every day. Increase that to 4.0 pCi/L and there are almost 2.5 MILLION explosions each minute. If there was a way for people to see these explosions each time they occurred, there is no doubt that everyone with a radon issue would have it repaired.

What happens when radon is measured?

When radon is measured, it is similar to a Geiger counter. Every time a Geiger counter makes a “tick” sound, it represents one of those radioactive explosions. the more it ticks, the closer they are to the source of the radiation. Radon tests do the same thing by counting the number of these explosions over a period of time. Those explosions determine the amount of radon that is in your home.

If you don’t like the idea of millions of little explosions occurring in your home each and every day, you should have your home tested for radon. If you results come back high, it is important to have a radon mitigation system put in.

Trinity Radon helps reduce the amount of explosions with radon reduction systems. If radon measured high in your home, give us a call today: 630-499-1492.

"The technicians at Trinity services were extremely professional. It was a pleasure to open up our home to them. My wife and I were extremely impressed with how neat and clean they worked. A lot of contractors just don't care, but I could tell that Trinity was not one of those...
