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

The picture above shows the average radon levels throughout the United States while the picture below shows the average radon concentrations in South Dakota.  The areas in pink 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.


The Numbers

-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

lung cancer)

-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

$1,200

-Average mitigation system operating cost in South Dakota $3.00/month

-Expected life span of fan

11 years

-Fan replacement cost

$145-$300  ($60-$100 if fan is under warranty)

-Test cost

$50-$100


Mitigation of radon gas

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 left shows 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.

The Problem of Radon gas in brookings watertown and sioux falls

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.
