Radon Testing Portsmouth, NH

1. Our Electronic Radon Monitor (ERM) is placed in the home at the lowest level.  The machine continually collects readings for a minimum of 48 hours.
2. During this time the home must be kept in “closed” condition to ensure the most accurate reading.
3. After sitting for 48 hrs collecting readings of Radon levels, the documented levels are reported and you are notified within a detailed report.
4. Levels are considered safe if they are below the threshold of 4 pCi/L (picocuries per liter of air) as stated by the EPA.  If the levels are above this threshold, other steps are needed for mitigation.

About Radon

Radon gas is harmful to human beings. It is a silent killer. Radon is odorless, colorless gas responsible for too many deaths per year that can be prevented easily. The only way to know the presence of radon gas in your home is to have a home radon test. It does not matter in which state or in what type of home you are living, radon testing is the only way to check the level of risk. Radon does not just appear in residential properties, it can appear in commercial buildings as well, so it is important for commercial properties to receive radon testing too. According to Environmental Protection Agency, there are various case studies that show that radon gas is seriously responsible for lung cancer.

Radon gas is produced from the decay of natural uranium in water, soil, and rock. This hot gas is present in the outdoor air and comes into homes through cracks found in a foundation or walls, construction joint, cavity inside walls, gaps in floors, service pipes, etc. According to the Environment Protection Agency, the radon gas comes with the homes from the soil in contact with basement floors and walls.
