What Is Radon?

Radon is a radioactive gas found naturally in a variety of minerals. It is tasteless, colourless and odourless, but can negatively affect human health. Radon can infiltrate basements through foundation cracks, service spaces and floor drains, and eventually reach upper floors.

Health Canada Guidelines

When radon reaches high concentrations inside buildings, it impacts air quality and becomes a health hazard, increasing the risk of illnesses such as lung cancer. The federal government adopted Health Canada’s radon guidelines in June 2007. These guidelines recommend taking corrective measures when the average annual concentration of radon exceeds 200 Bq/m3 in common indoor areas.

Radon Assessment

Le Groupe GESFOR offers a wide range of radon evaluation services:

  • Developing sampling strategies for buildings according to occupation rates and types of rooms
  • Installing and collecting reading equipment (electret ion chambers or alpha track detectors) for long-term sampling in buildings
  • Providing technical support during the installation of detectors by our clients
  • Performing short-term sampling with Continuous Radon Monitors (CRMs) according to work schedules and occupancy loads
  • Sampling and analyzing water
  • Drafting reports with recommendations

Our consultants are certified by the American Association of Radon Scientists and Technologists (AARST) through its Canadian National Radon Proficiency Program (C-NRPP). Presently, we have the largest number of C-NRPP-certified specialists in the country. This certification is recognized in Quebec by Health Canada.

Additionally, our services are backed by independent laboratories, which are also certified by the AARST/ C-NRPP.

Radon Mitigation

Once long-term sampling of radon is completed, if concentrations are found to exceed 200 Bq/m3, Health Canada recommends performing radon mitigation.

We offer the following services:

  • Conducting detailed analysis of radon infiltration routes in buildings
  • Reviewing building plans
  • Performing feasibility testing for sub-slab depressurization mitigation systems
  • Selecting appropriate mitigation methods
  • Designing radon mitigation systems
  • Preparing detailed plans and specifications for radon mitigation
  • Prequalifying contractors
  • Carrying out project management and monitoring of radon mitigation work
  • Conducting systems diagnostics upon implementation
  • Taking post-installation readings

Many of our consultants are AARST/C-NRPP-certified radon mitigation experts. Moreover, our senior team members have undergone specific training for radon mitigation in large buildings (institutional buildings, office buildings, etc.).

TRAINING

We offer C-NRPP certification training for radon measuring and mitigation, as well as awareness training for building managers, owners, and occupants.
