The particles emit cancerous growth so you must ensure safe radon levels are recommended for you and your family

Safe Radon Levels

  • EPA Guidelines: Explanation of the EPA’s recommended safe radon level of 4.0 pCi/L or lower.
  • Acceptable Radon Levels: The safe radon level recommended is 4pCi/L. However, radon levels up to 4pCi/L can be threatened so radon levels should be reduced to 2pCi/L or below.

Measuring Radon Levels

  • Radon Testing Methods: There are two methods widely used: long-term tests and short-term tests short term takes up to 3-7 days whereas long term takes up to a period of 9 months to a year.
  • Frequency of Testing: Moreover, professionals recommend radon detection testing every two to three years to ensure safe radon levels.

How To Test For Radon?

  • Interpreting Results: Moreover, if the test result is below 2pCi/L it is a good result whereas, anything above 4pCi/L is dangerous. 
  • Actions for High Radon Levels: Furthermore, Researchers recommend having an active radon sump fitted with a fan which is an effective way to reduce the indoor radon level.

 What Level of Radon is Dangerous?

Dangerous Levels: when breathing radon it gets in the lining of the lung and gives off radiation which over time leads to the development of lung cancer.

  • Immediate Actions: Furthermore, a radon detector can help ease the process but the most common actions are increasing underfloor ventilation and sealing cracks. 

Reducing Radon Levels in Your Home

  • Mitigation Techniques: Furthermore, By using depressurization is a reliable method for radon reduction levels. If a first timer you can get a free radon test kit from local authorities if contacted.
  • Professional Help: additionally, If the test results come above 4pCi/L contact the radon service provider in your area or the national program.
