Radon is a naturally occurring radioactive gas that forms from the decay of uranium in soil, rock, and water. It is colorless, odorless, and tasteless, making it imperceptible to human senses. Radon can enter homes and buildings through cracks in the foundation, gaps in floors and walls, and openings around pipes and cables.
Exposure to high levels of radon over time can pose serious health risks, as it is a known carcinogen. Prolonged inhalation of radon gas can increase the risk of developing lung cancer, particularly among smokers. Radon is considered the second leading cause of lung cancer after smoking, according to the U.S. Environmental Protection Agency (EPA).
Testing for radon levels in homes and buildings is essential to assess potential health risks. Radon mitigation techniques, such as ventilation systems and sealing cracks in foundations, can be implemented to reduce radon levels and minimize exposure.
Radon tests are available in New Hampshire. You can obtain radon test kits from various sources, including local hardware stores, home improvement centers, or online retailers. Additionally, you can hire a qualified radon measurement professional to conduct the test for you.
There are different types of radon tests, including short-term tests that typically last 2 to 7 days and long-term tests that extend over 90 days to a year. Some common types of radon tests include:
-
Charcoal Canister Tests: These are passive devices filled with activated charcoal that absorb radon gas. After the test period, the canisters are sealed and sent to a laboratory for analysis.
-
Alpha Track Detectors: These passive devices use special materials to record alpha particles emitted by radon decay. After the test period, the detectors are sent to a laboratory for analysis.
-
Electronic Continuous Radon Monitors: These are electronic devices that continuously measure and record radon levels over time. They provide real-time data and are often used for both short-term and long-term testing.
Before conducting a radon test, it's important to carefully follow the instructions provided with the test kit to ensure accurate results. If you prefer professional assistance, you can hire a certified radon measurement professional who can conduct the test and provide you with the results.
If elevated radon levels are detected, mitigation measures can be taken to reduce radon exposure and ensure a healthier indoor environment. It's crucial to address radon issues promptly to protect the health of occupants.
Can a General Building Inspector conduct a Radon Air Test?
In New Hampshire, general building inspectors may or may not be qualified to conduct radon air tests. It depends on the individual inspector's qualifications, training, and certifications.
While some building inspectors may offer radon testing as part of their services and may be certified to perform such tests, others may not have the necessary expertise or equipment for radon testing.
If you're considering having a radon air test conducted by a building inspector in New Hampshire, it's essential to inquire about their specific qualifications and certifications related to radon testing. Alternatively, you can hire a qualified radon measurement professional who specializes in radon testing and mitigation to ensure accurate results and compliance with state regulations. These professionals typically have the expertise, equipment, and certifications necessary to perform radon testing accurately and reliably.
Radon mitigation is the process of reducing radon gas concentrations in homes or buildings to minimize the health risks associated with radon exposure. Mitigation techniques aim to prevent radon gas from entering indoor spaces or to remove it once it has entered. Common radon mitigation methods include:
-
Sub-Slab Depressurization: This method involves installing a vent pipe and fan system beneath the concrete slab foundation of a building to create a vacuum effect, which draws radon gas from the soil and vents it safely above the roofline, where it disperses harmlessly into the outdoor air.
-
Sump Pump Depressurization: If a building has a sump pump or drainage system, it can be modified to act as a radon mitigation system. A vent pipe is attached to the sump pump pit, and a fan is used to draw radon gas from beneath the building and exhaust it outdoors.
-
Sealing Cracks and Openings: Cracks in foundation walls, floors, and other openings in the building's structure can serve as entry points for radon gas. Sealing these gaps with caulking or other sealants can help prevent radon from infiltrating indoor spaces.
-
Ventilation Systems: In some cases, increasing ventilation in a building can help dilute radon gas concentrations. This may involve installing additional vents, fans, or air exchange systems to improve airflow and reduce radon levels.
-
Crawl Space Encapsulation: In buildings with crawl spaces, encapsulation involves sealing the crawl space to prevent radon gas from entering. This may include installing a vapor barrier, sealing vents, and ensuring proper drainage to prevent moisture buildup.
Radon mitigation systems should be designed and installed by qualified professionals to ensure effectiveness and compliance with local regulations. After installation, periodic testing is recommended to verify that radon levels remain below recommended thresholds and to ensure the ongoing safety of indoor air quality.
Radon can also be present in water, particularly in areas where groundwater contains high levels of uranium, which naturally decays to form radon gas. When water containing radon is used for activities such as showering, cooking, or washing dishes, radon can be released into the air and potentially inhaled, posing a health risk.
To determine if radon is present in your water, you can have a water test conducted by a certified radon measurement professional or a state-certified laboratory. Water tests for radon typically involve collecting a sample of water from your tap and sending it to the laboratory for analysis.
If elevated levels of radon are detected in your water, there are several mitigation options available to reduce radon exposure:
-
Aeration: Aeration involves agitating the water to release radon gas, which is then vented to the outdoors before the water is used.
-
Granular Activated Carbon (GAC) Filtration: GAC filters can effectively remove radon from water by adsorption onto the carbon surface.
-
Point-of-Entry (POE) Treatment Systems: POE treatment systems are installed at the point where water enters your home and can treat all the water used in your household.
-
Point-of-Use (POU) Treatment Systems: POU treatment systems are installed at specific water sources, such as kitchen faucets or showers, to treat water only at those locations.
It's essential to consult with a qualified radon mitigation professional to determine the most appropriate mitigation solution for your specific situation. Regular testing and maintenance of water treatment systems are also important to ensure their effectiveness in reducing radon levels.
