Radon is a naturally occurring radioactive gas that is formed by the breakdown of uranium in soil, rock, and groundwater. It is a colorless and odorless gas that moves freely through the soil and in enclosed spaces, such as buildings, it can accumulate resulting in high concentrations. Radon can enter buildings through cracks in foundation walls and floors, and any gaps around pipes and cables. Radon exposure is known to cause an increased risk of developing lung cancer and is the second leading cause of lung cancer behind smoking.
As a result, maximum exposure limits have been established around the world and in order to control radon infiltration, building codes and standards are continuing to develop to incorporate radon mitigation systems. The systems that have been deemed effective can be described as active and passive.
We have recently released a technical bulletin for both the U.S. and Canada to go into further detail about radon guidelines, proper testing, and radon depressurization methods. To avoid excessive radon permeation, W. R. Meadows’ PERMINATOR and PRECON underslab barriers have been designed and tested to meet the industry standards for underslab construction and radon resistance.
