== == That's just barely over the limit. However the EPA action level of 4 pCi/L is NOT a safe level. The Death Rate the EPA uses, 21,000 deaths per year, is not calculated using 4 pCi/L, it is calculated using the average U. S. home Radon level, 1.3 pCi/L. There is no safe level of Radon. Usually a mitigation system must take the level below 2 pCi/L to be considered acceptable. Call in a professional Radon mitigator to find out where the Radon is coming into the home. They are experts at ventilation, some depressurize the soil beneath the home.

Sealing is rarely an effective treatment for radon reduction. If you have an unfinished basement and your level is between 4-8pCi/L it may be worth a try. But use a good quality urethane caulk to seal all concrete areas as silicone caulk will not hold up.

If a home has a radon level of 4.3 pCi/L or above, it is recommended to take action to reduce the radon levels. This can involve hiring a professional radon mitigation contractor to install a radon mitigation system in the home to lower radon levels to an acceptable range. It is important to address high radon levels to reduce the risk of lung cancer associated with long-term radon exposure.

Is 3 WL a high radon level?

Yes, a radon level of 3 WL (picocuries per liter) is considered high and poses a potential health risk. The Environmental Protection Agency (EPA) recommends taking action to reduce radon levels if they exceed 4 picocuries per liter. It is advisable to contact a professional to mitigate the radon levels in your home.


Why do you have to have a radon test done on your house in PA?

Having a radon test done on your house in PA is important because radon is a radioactive gas that occurs naturally in soil and can seep into homes through cracks and openings. Prolonged exposure to high levels of radon can increase the risk of lung cancer. Testing for radon is the only way to know if it is present in your home and if mitigation measures are needed to reduce it to safe levels.


What can be done to prevent or decrease radon exposure in your home?

To prevent or decrease radon exposure in your home, you can: Test your home for radon levels regularly. Seal cracks and openings in the foundation and walls. Improve ventilation in your home. Install a radon mitigation system if levels are high.


What is a radon gas testing home kit?

A radon gas testing home kit is a tool used to measure the levels of radon gas in a home. It typically includes a radon detector and instructions on how to set it up and collect air samples. Testing for radon is important as prolonged exposure to high levels of radon gas can be harmful to health.


Can radon get into a home with an exposed basement?

Yes, radon can enter a home with an exposed basement through cracks in the foundation or gaps in the basement floor. It is important to test for radon levels in basements, especially if they are unfinished or exposed. Mitigation measures such as sealing cracks and installing a radon mitigation system can help reduce radon levels in the home.

Protecting from Radon Gas?

Radon gas can be a silent killer, so anyone who has an older furnace, one that is powered by coal, or anyone living in an area of high radon concentrations should have a radon gas detector. These are extremely simply to install in an home. the unit will either be battery power or need to be plugged into the wall. Once turned on, the unit will display a number that corresponds to the radon level. If this number gets too high, an audible alarm will go off to alert the family. This simple device can help to keep a family safe.

If a home has radon levels of 4 pci how many people would get cancer?

The risk of developing lung cancer due to radon exposure is estimated to increase by 16% for every 100 Bq/m³ increase in radon levels. However, it is important to note that individual susceptibility, duration of exposure, and other environmental factors also play a role. Therefore, it is not possible to determine an exact number of people who would develop cancer based solely on the radon level in a home.


Does a dehumidifier help reduce radon any?

A dehumidifier can help to reduce moisture levels in a home, but it will not directly reduce radon levels. To reduce radon levels, you would need to implement radon mitigation techniques such as sealing cracks in the foundation or installing a radon mitigation system.


What does radon cause?

Radon gas can cause lung cancer after smoking. Non-smokers can get them as well. Gas rises up underneath the homes if there is low pressure in the house, and it can act like a vacume. Radon gas is the heaviest gas of all, so it should be sitting on the flours. High levels of radon is like smoking 135 cigarette packs a day. There are radon detection kits and radon extraction services. The extraction services may cost as much as a small home repair.
