Home Radon Testing

Building Knowledge conducts radon testing according to EPA protocols. We place the testing mechanism and complete the reading onsite after the minimum 48 hour test period.

“Radon is a cancer-causing natural radioactive gas that you can’t see, smell or taste. Its presence in your home can pose a danger to your family’s health. Radon is the leading cause of lung cancer among non-smokers. Radon is the second leading cause of lung cancer in America and claims about 20,000 lives annually” (epa.gov).

Radon Testing Procedure

Building Knowledge utilizes an E-Perm radon test device. “An E-PERM®, also known as an Electret Ion Chamber (EIC), is a passive integrating ionization monitor consisting of a very stable electret mounted inside a small chamber made of electrically conducting plastic. The electret, a charged Teflon® disk, serves as both the source for ion collection and as the integrating ion sensor. Negative ions produced inside the chamber are collected on the positively charged electret, causing a reduction of its surface charge. The measurement of the depleted charge during the exposure period is a measure of integrated ionization during the measurement period. The electret charge is read before and after the exposure using a specially built non-contact electret voltage reader referred to as the SPER-1 Electret Voltage Reader. Using this data as input to the appropriate formula, one can determine the radon activity present over the duration of the test” (radelec.com).
