Professional Radon Testing in Bethesda
Although radon poisoning isn’t as well known or as prevalent as carbon monoxide poisoning, radon is responsible for thousands of fatalities every year. Exposure to it is the leading cause of lung cancer in non-smokers.
Since it’s a colorless and odorless gas, it can only be detected through testing. You could purchase a DIY test kit, but these have many disadvantages that could give inaccurate results.
Hiring a professional radon inspection company is the best method to regain confidence in your safety and health within your Bethesda home. Radon Defense will ensure your radon testing and mitigation are efficient and affordable.
What is Radon?
Radon is a naturally occurring radioactive element found in soil and rock. Radon does little harm as an element, but it decays into two other elements: polonium (Po) and lead (Pb) which are health risks. Po has a half-life of 138 days, while Pb has a half-life of 2 years. Both Po and Pb are highly toxic and carcinogenic.
According to the EPA, radon increases the risk of lung cancer almost as much as cigarette smoking. It’s estimated that over 4 million lung cancer deaths each year are due to radon exposure.
Is Radon a Problem in Maryland?
Yes, radon is a serious issue in Maryland. Radon is found throughout the state, especially near underground sources such as coal mines. If you live in one of these areas, you should consider having your home tested by a licensed radon inspector.
Radon levels in a house depend on rock presence on the foundation and if there are entry points into the crawl spaces or basements. This map of radon levels in Maryland shows how radon levels differ throughout the state.
The radon levels in Maryland range from 0-4 pCi/L:
- 0 – 1 pCi/L – Low-risk level
- 1 – 3 pCi/L – Moderate risk level
- 3 – 6 pCi/L – High-risk level
- 6+ pCi/L or above – Extremely high-risk level
Is Radon Testing Required in Maryland?
When purchasing a house in Maryland, rating testing is optional. However, in Montgomery County, things are different. A law was passed in October 2016 which requires a house to be tested during a real estate transaction.
These test results shouldn’t be over a year old when completing the sale. Some homeowners in Bethesda test their homes for radon before they list their houses for sale. But for those that don’t, the homebuyer has to have the house tested for radon.
Our professionals are experienced and certified in radon testing and mitigation in Bethesda. Get in touch with us, and one of our specialists will be happy to answer any questions you might have and help you schedule a site visit before installation.
The EPA sets radon’s action level at 4 pCi/L (picocuries per liter). Results at or above this radon level require mitigation to protect your family’s health. The average outdoor radon levels are 0.4 pCi/L, and the average indoor radon levels are 1.25 pCi/L. Reducing radon levels to such levels requires efficient radon reduction systems that use specialized equipment to remove radon from the air.
There are two main ways to mitigate radon gas levels in your home. They include:
- Air Exchange Ventilation Systems
An air exchange system uses negative pressure to pull radon out of the house and into an exhaust fan where it can be removed from the home. This method works well for homes built before 1980 because these homes were designed without adequate ventilation. However, newer models are required to have an air exchange system installed.
- Ventilation Fans
A ventilation fan pulls outside air through cracks and holes in the walls and floors. The fan creates a draft that pushes indoor air out of the home. An air exchange system combined with a ventilation fan reduces radon levels significantly.
Do Passive Radon Systems Work Efficiently?
Yes! Passive radon systems are effective in reducing radon levels inside homes. When used correctly, they provide a cost-effective solution to reducing radon levels.
However, the effectiveness of passive radon systems depends on the quality of the installation. If the system isn’t sealed properly, it’s not as effective.
