Does opening windows reduce radon?
As a temporary solution, however, you can reduce radon levels simply by opening windows. Opening windows improves air circulation and ventilation, helping move radon out of the house and mixing radon-free outside air with indoor air. Make sure all your basement windows are open.
What time of day is radon highest?
During the day, the sun beats down and heats up the house from the outside in, but at night, there is a rapid cooldown. This results in slightly higher radon levels during the day, rather than at night.
What season are radon levels highest?
winterIndoor radon levels are normally at the highest in the winter or colder months because of the thermal stack effect, a snowy barrier, and tightly sealed homes. Cold temperatures increase the pressure within the home, meaning more air is being pulled in from the ground, which elevates the risk of radon entering the home.

Feel free to use central air conditioning to keep your house cool during radon testing. Be careful, though, when using window and wall air conditioning units, as no air from the outside should enter the house.
Does running furnace affect radon test?
2 Winter is a good time to test for radon gas. Winter is a good time to test for radon because you are, in-most cases, measuring the worst case scenario for your home. With the hatches battened down and the furnace running, you are creating a scenario that can cause radon levels to be higher.
Does radon gas sink or rise?
Radon and other gases rise through the soil and get trapped under the building. The trapped gases build up pressure. Air pressure inside homes is usually lower than the pressure in the soil. Therefore, the higher pressure under the building forces gases though floors and walls and into the building.

What is ASD in crawl space?
There will be an ASD (active soil depressurization) system installed, followed by a vapor barrier. I read an EPA study that stated ASD was by happenstance greater overall at dehumidifying a crawl space because it was pulling the damp soil from underneath the vapor barrier, which left little humidity to permeate the vapor barrier.
Why do we use scrubbers in the crawl space?
We use scrubbers in the home in the event the soda comes in and with the force it has, it usually does. We use negative air machines in the crawl to push soda out and try to keep out of home.
Does sealing a radon vent affect the vapor barrier?
Sealing the vents may have an effect on the radon fan but if the ASD is installed and sealed correctly there will be very little air movement above the vapor barrier. When the vapor barrier is installed it is sealed with polyurethane caulk to prevent air movement except under the vapor barrier. You may decide to add a foundation vent fan blowing out in order to make sure the air above the vapor barrier is not entering your home.
Do you need a vapor barrier for termite gaps?
I think you should have your contractor take the vapor barrier all the way up the wall. If your state requires a termite gap, be sure to abide by local codes. The vapor barrier up the wall will help minimize moisture from rain and humidity. This should allow the radon fan to work even better at keeping the humidity low.
Does radon raise humidity?
While researching information about your question, I came across an inspector that concluded the radon fan was actually raising the humidity levels in a home. This is why I say all homes are different and humidity levels should be checked to ensure what your ASD is doing. I found the information on the Green Building Advisor Community and Q&A. He said:

Short-term radon test kits often require you to send the kit to a lab for analysis, while long-term detectors can actively gauge radon levels in your home and give you a reading within hours (although at least as week is recommended to ensure accurate readings). Testing water for radon, on the other hand, always necessitates sending a sample of your home’s water to a laboratory for analysis.
What is radon mitigation?
The purpose of a radon mitigation system. A radon system or radon mitigation system is one that actively removes radon gas from your home, usually by removing the gas from below the building and expelling it above and away from the building. Radon mitigation removes radon gas from breathable air, sometimes also removing radon from drinking water.
How does radon enter a home?
Radon can also enter the home via the materials used to build the home, and this requires a type of radon system called “mechanical ventilation.”. In some cases, radon can form in pockets around buildings, and ventilating these pockets effectively removes the radon from near the outside of the building.
Why is radon in my home different in summer?
Factors to consider. Various factors affect levels of radon in your home, and because it is a gas these levels will fluctuate over time. So, in the summer the levels of radon in your home may be different than in the winter. For this reason, a long-term monitoring approach is recommended, as opposed to a short-term test ...
How much moisture does a humidifier add to the air?
A typical humidifier adds 2 pints per hour. If you live east of the Rockies however, infiltration from outdoor warm humid air in the summer months can add 50 to 250 pints to the indoor air per day. So during the summer any infiltration increase to the basement will significantly increase the humidity and possibility of mold. Ventilating the basement for moisture reduction can only be done when the dew point is below the optimal indoor dew point.
How to test capillary transfer?
To test a basement slab for capillary vapor transfer lay a rubber mat or poly sheet on the slab during a rainy period for a few days and see if moisture droplets collect on the barrier.
What is a Humidex system?
The Humidex system is basically an exhaust fan that ducts air off the floor of the basement to the outside with advertised claims that it reduces humidity. While this system will increase basement ventilation it accomplishes it by slightly de-pressurizing the basement area.
Why is my basement foundation wet?
Wet basement foundation walls are often due to bad roof gutter systems and or grading problems. The roof collects a lot of water from rain water. Many wet foundation walls can be dried up if all the roof downspouts drained their water at least ten feet from the house to a location where it won't drain back to the house. If corner of a foundation wall is wet it is almost always the same corner where a downspout drops it's water next to the foundation . Clogged gutters, improperly sloped, downspouts emptying next to the foundation are all major culprits of wet foundation walls. Check all your gutters and downspouts and install piping to get that water away from the house.
Why are mold spores inactive?
Small amounts of mold and mold spores are ever present in our homes but they are mostly inactive because of lack of necessary moisture. Mold spores begin to rapidly multiply when the relative humidity level goes above 60%and the temperatures are between 50 and 90 degrees F. and there is little air movement.
What temperature does mold grow?
Mold spores begin to rapidly multiply when the relative humidity level goes above 60%and the temperatures are between 50 and 90 degrees F. and there is little air movement. The EPA has stated there is a connection between mold exposure and, asthma and chronic sinusitis.
How many sources of moisture are there in a basement?
There are four sources of basement moisture:
How to get rid of radon in soil?
The most effective way to get rid of radon is to install a removal system that draws the radon out of the soil before it even has an opportunity to enter the house. These systems are called "Sub Slab Depressurization Systems" or "Active Soil Depressurization Systems". These systems operate by using a piping and fan system that depressurizes the soil that surrounds the home. This in effect reverses the pressure differential between the soil and the lower portion of your home. You'll still have the same pressures within your house that you've always had and never noticed, but the radon will be vented safely outside so that it can dissipate harmlessly into the atmosphere. It doesn’t take much of a pressure differential to draw radon into a home, and it doesn’t take a lot of pressure to draw it out.
What are the benefits of radon removal?
Of course the single largest benefit of having a radon removal system is low radiation exposure and a greatly reduced chance of getting cancer , but many other benefits have also been reported. As radon removal systems safely exhaust the radon, they also remove other chemicals and gases that are commonly found in the soil around our homes like insecticides, pesticides, herbicides, methane, and carbon dioxide. Cleaner air means better health. These systems also remove moisture from the ground and can help to keep basements drier and prevent mold growth. Smart home buyers are now asking for a radon test as part of the inspection process so if you already have a radon removal system in place, you may sell your home faster or even get more for it. One of the biggest benefits though is peace of mind and knowing that you’re doing the right thing for yourself and your family.
