New Hampshire has some of the highest indoor radon levels in the country.
Radon is a colorless, odorless gas that can build up indoors without anyone knowing. Over time, it can increase the risk of lung cancer. New Hampshire has some of the highest indoor radon levels in the country, so testing is one of the simplest ways to protect the people who spend their days in your building. The only way to know if your workplace is safe is through professional radon testing.
At The Lawson Group, we help businesses, schools, and organizations throughout New England identify risks and understand next steps. Our safety & health consultants provide clear testing results and practical advice on how to keep your team safe.

How Radon Testing Works
Our team uses professional monitoring equipment to measure indoor radon levels and compare results against EPA radon guidelines.
Short-term testing
For quick initial results.
Long-term monitoring
To capture seasonal and usage changes.
Post-mitigation testing
to confirm that a system is working effectively.
Why Radon Testing Matters
Radon is the second leading cause of lung cancer in the U.S. after smoking. Because it builds up indoors without warning, workplaces that ignore radon risk put employees’ long-term health in jeopardy. Workplaces most at risk include:
Basements and ground floors, where radon gas accumulates
Homes, schools, and offices on granite-rich soil (common in NH)
Older buildings with cracks, poor ventilation, or outdated construction
Meeting EPA Radon Guidelines
The EPA recommends action at 4 pCi/L or higher. Even levels below that can pose risks over time. We help you:
Understand
Understand your radon testing results in plain English.
Compare
Weigh mitigation options and choose the right partner for installation.
Monitor
Confirm ongoing compliance with EPA and OSHA standards.
Our Role: Testing & Consulting, Not Installation
The Lawson Group does not install radon mitigation systems. What we do is just as important: we test for radon, interpret results, and act as your trusted advisor on next steps.
If your building needs mitigation, we’ll connect you with qualified contractors and help you understand which system is best for your situation.
Radon FAQs
The EPA recommends testing every two years, or sooner if building renovations or HVAC changes occur. Schools should test regularly since children are especially vulnerable to radon exposure.
Yes. Even after a system is installed, radon levels can change. Post-mitigation testing ensures the system is still working properly.
While radon is strongest in basements and ground levels, it can circulate throughout a building through HVAC systems, stairwells, and air movement.
If your test shows elevated radon, we’ll review the results with you and recommend qualified mitigation contractors. We’ll also perform follow-up testing once a system is installed to ensure effectiveness.
OSHA doesn’t have a specific radon standard, but employers are required to provide a safe workplace. Using EPA radon guidelines is considered best practice for protecting employees.
