Measuring radon in the home and other buildings

The level of radon in a home or building cannot be predicted reliably, so needs to be measured with a radon detector. Radon can get into buildings from the ground below and varies from home to home and by lifestyle.
Radon detectors are safe and simple to use e.g. they can sit on a shelf. They are small hollow plastic shells containing a piece of clear plastic that records the damage caused by radon.
 
The detectors do not release or collect anything dangerous. However, they can be damaged by heat or submersion in water and should not be opened.
  
The amount of radon varies over time and from room to room in a home. The test is carried out over three months to allow for variations in levels.
 
The test is to determine your exposure, therefore, we recommend testing the living area and bedroom as these are the rooms you and your family use the most.
