| Radon Testing |
|
|
- There are two types of radon testing devices, Passive and Active.
|
- Passive devices do not need power to function and are relatively inexpensive.
|
- Active radon testing devices require power to function and usually provide hourly readings and an average result for the test period. These include continuous radon monitors and continuous working level monitors, and these tests may cost more but, are more accurate.

Measurement of Radon
- Radon levels are commonly expressed in picocuries per liter of air (pCi/L), where a picocurie is a measurement of radioactivity.
- The national average of indoor radon levels in homes is about 1.3 pCi/L. Radon levels outdoors, where radon is diluted, average about 0.4 pCi/L.
