Radon is a gas byproduct that comes from naturally decaying uranium within the earth. It is odorless, tasteless and colorless making it impossible to spot without help from a detection system. Of all of the gases, it is the only one under regular conditions that has radioactive isotopes. It can pose a health hazard because of the intense radioactivity. This radioactivity also makes it difficult for scientists to study radon. It is easily inhaled making it a hazard for many.
In some construction situations it may be warranted to hire someone that can detect radon. This might occur if you are digging in large depths for construction of a building or other structure. In addition, there have been reports of radon in homes in some areas. Having a radon test conducted in your home is something to consider if you are in an area where there may have been some disruption. Some areas of the United States, Ireland and Canada have higher levels of the gas byproduct reported. In some cities there have been requirements set up that require newly constructed homes to be radon resistant in an effort to protect against the radon that might come up through the various ground levels.
