What is Radon?

Radon is a radioactive decay product of radium, you cannot see, feel, smell or taste .  It is found at low concentrations in almost all rock and soil.  Radon is generated in rock and soil, and it creeps through cracks or spaces between particles up to the outside air.  Although outdoor concentrations of radon are typically low  (0.4 pCi/L), it can seep into buildings through foundation cracks or openings and build up higher concentrations indoors, if sources are large enough.  The indoor radon concentration in a can vary from house to house.  

Testing the home / building is the only way to know if there is a risk from radon.  The first step is to test your home / building for radon and have it fixed (mitigated) if it is at or above the EPA's action level of 4 picocuries per liter (pCi/L) for indoor air.  You may consider to take action if the levels are in range of 2-4 pCi/L.  Generally, levels can be below 2 pCi/L fairly simply.  The action level is not the maximum safe level for radon in the home.  However, the lower the level of radon the better.  

Types of Radon Testing

I - Radon Testing

Our Single and Two Family radon testing is done in accordance with the current ANSI/AARST protocol (MAH-2023).   Radon detectors will be placed in lowest livable level of the building and will be left exposed to for a period of 48 - 144 hours.  The radon detectors will be submitted to the laboratory and results emailed to the client in approximately 3-days. 

II - Multi-point Commercial Radon Assessment 

Radon levels can vary throughout, especially in larger spaces like Childcare centers, Schools, Multi-family (3 or more units), Mixed-Use, and Commercial buildings.  Testing just one area will not provide an accurate picture.  Our Multi-point Commercial Radon Assessment is done in strict accordance with the current ANSI/AARST protocol (MA-MFLB-2023).  It use multiple detectors placed in key locations to evaluate radon levels throughout the building.  The process includes third-party laboratory analysis and quality control validation to ensure results are accurate, reliable and defensible.  

Our  process has 4 phases 

1. Site Assessment & Planning - We visit the property, develop site plan, and determine number of testing locations

2. Quality Control Preparation - We coordinate third-party validation and laboratory preparation for testing accuracy

3. Device Deployment & Testing - We deploy radon detectors throughout the building and monitor for 48-72 hours

4. Laboratory Analysis & Reporting - The radon detectors are analyzed by a certified laboratory and prepare a detailed report

The entire Multi-point Commercial Radon Assessment process is approximately 3-4 weeks.
