If you’ve done Testing for Radon in your home and you’re confirm that your house has eminent Radon level (higher than 4pCi/L), then this is what you’ve got to do next.
Steps for reduction of Radon in your house include the selection of an experienced Radon Mitigation contractor; choosing an appropriate method of mitigation; upholding your reduction method.
How does it work?
According to US EPA, unavailability of appropriate equipment and technical knowledge, you may end up elevating the level of radon. So you must have a qualified service provider who has practical skills and technical knowledge in this field. Radon reduction systems are capable of reduction by up to 99 percent and they cost depending upon the size of your house and its design.
Likewise, New York State Department of Health Radon Program can provide you with proper training and information if you tend to work on your own.
Selecting A Service Provider.
American Society for Testing and Materials (ATSM) follows industry consensus standards that must be held by the contractor.
There are some steps you should follow for the selection of a service provider.
· Evaluation of The Contractors
Contractor must be able to explain what the work involves and in what time it can be done. You must see if contractor does the estimate by checking the structure of your house.
· Signing a contract
You must make a contract which may completely describe the work that is to be done. Read the terms and conditions of the contract carefully before you sign it. The contract must include the total cost and the time needed to complete the job, a guarantee that the contractor will be responsible of any damage to the property during the work and declaration that warranties are transferable in case of selling of the property.
· Comparing the Costs
You must compare the costs of contractors and rethink what you’re going to get for your payment. Less expensive systems cost more while operation and maintenance. While expensive systems cost less during operation and maintenance.
Types of Reduction Methods.
In the homes having slab foundations and basements, Radon Mitigation is done by the following suction methods
· Subslab Suction
Subslab depressurisation is done through inserting suction pipes into the soil underneath the slab of floor or the extruded rock. It is the most irreproachable and reliable method of suction. Passive Subslab Suction is the second type of subslab suction and it depends upon pressure differentials and air currents. At it is installed in new made houses. Yet it’s not as effective as active subslab suction.
· Drain-tile Suction
Homes having perforated pipes for direction or water away from the foundation. Suctions are applied on these pipes to lower the radon level.
· Sump-Hole Suction
It’s one variation of both the drain-tile and subslab suction methods. Some homes have basements having sump pump for removal of untoward water.
· Block-wall Suction
It is similar to subslan suction and is used in coordination with subslab method. It is used in basements as hollow block foundation walls.
Radon in Water
If Radon Mitigation in the air doesn’t seem to work reduce radon level, then radon in water is thought to be pathway. Whilst it may result in an inhalation risk.
