These days it is very important to take care of your lung health, and radon in your house can have an adverse effect on your lungs. Radon is a radioactive, colorless, odorless and tasteless gas that is formed as uranium deposits in the Earth's crust decay. Exposure to radon is the second leading cause of lung cancer behind smoking. Radon can enter buildings through many paths such as: cracks in foundations, utility penetrations, sumps, and floor drains. The ventilation of buildings effects the final radon concentration. The EPA has made the recommendation of no long-term exposure to be over 4 Pic/L.. If a house is at 10 Pic/L of radon, living in this space is similar to smoking a pack of cigarettes a day. The problem can be solved by installing a radon mitigation system.
-21,300 lung cancer deaths per year are
due to radon exposure in the home
-18,400 deaths are among those who have
smoked (12% of all smokers who die from
-2,900 of these deaths are among those
who have never smoked (26% of all
smokers who die from lung cancer)
-Average mitigation system installation cost
$1,100-$1400 however the price may vary home to home
-Average mitigation system operating cost in South Dakota $3.00/month
-Expected life span of fan
-Fan replacement cost
$145-$300 ($60-$100 if fan is under warranty)

The areas in pink on the map above have dangerous radon levels on average,the images in yellow have moderate radon levels and the areas in blue are typically low. These maps should not be used as a substitute of an actual radon test. Everyone should have their home tested to ensure their health and safety. As you can see, all the counties in the Brookings, Watertown and Sioux Falls area have above average radon levels that are known to cause health problems such as lung cancer and asthma
If you find that your home has high radon levels, there are ways to reduce the concentrations. Even very high levels can be reduced to acceptable levels by installing radon mitigation in Brookings and surrounding areas. There are several methods that can be used to lower radon gas levels in your home. Some techniques prevent radon from entering your home while others reduce radon levels after it has entered. EPA generally recommends methods which prevent the entry of radon. One method that prevents the entry of radon is called active soil depressurization. This system consists of PVC pipe connected to the soil either through a hole in the slab, a sump lid connection, or beneath a plastic sheet in the crawl space. Attached to the pipe is a quiet, continuously operating fan that discharges the radon to a location outside of the home. The picture below shows a mitigation system that was installed on an existing home while the picture to the leftshows a system that was installed on a house while it was being built. This pipe will not be visible once the house is complete because it will be hidden in the walls. The radon mitigation system cost is very small compared to the health benefits that you receive from having a radon mitigation system installed.
There are many companies in the area who perform radon mitigation, however it is very important to find someone who is certified through the NRPP and AARST. Companies that are not certified often perform the work in ways that can actually do more harm than good! Be sure to check out the NRPP or AARST website to find a certified professional near you. https://certifiedradonpros.org/index.html
C and S is one of the only companies in Eastern South Dakota that is certified through the NRPP to perform radon mitigation. Being certified means that they have to hold themselves to a very high standard with all of their mitigation systems. C and S strives to bring radon levels in customers' houses to the lowest possible number. This ensures that the residents will not have to worry about the negative affects of radon in their home.
Common Things that people do wrong at installation:
Putting the fan in the basement.
-the radon fan should never be located in the living space of a home. It should always be located in an attic or outside the house
Venting the radon out the side of the house under windows
- radon gas needs to be vented either 10 feet away from the nearest window, or 2 feet above the nearest window. This typically means that the piping needs to be vented above the roof of the house, either through the eve or around the eve. If a company tells you that they can vent it like a dryer vent, THEY ARE WRONG. This could lead to concentrated radon coming back into your home.
