The exploration of radon is credited to Friedrich Dorn (), a German physics teacher. Marie Curie's experiments boosted Dorn to begin researching the phenomenon of radioactivity. In 1900, he showed that radium sent out a radioactive gas that was called radium emanation for a number of years.
Radon Levels by Postal Code & State
What is radon used for today?
Radon levels are measured in picocuries per liter, or pCi/L. Levels of 4 pCi/L or higher are considered hazardous. Radon levels less than 4 pCi/L still pose a risk and in many cases can be reduced, although it is difficult to reduce levels below 2 pCi/L. Once installed, a follow-up radon test is done.
What this does is draw radon gas from the ground and remove it with an air vent, usually in the roof. According to Health and wellness Canada, radon is linked to professional radon testing equipment about 16% of all lung cancer cells fatalities in Canada. That makes radon the 2nd leading reason for lung cancer after cigarette smoking.

The revealed earth in crawl rooms, basements, or under manufactured residences is covered with an impermeable membrane layer like impermeable poly vapor barrier.
Is radon really dangerous?
When radon gas enters the body, it exposes the lungs to small amounts of radiation. In small quantities, experts say this is harmless. However, in persistent exposures or larger quantities, radon can damage the cells of the lining of the lungs, increasing a person's chance of developing lung cancer.
The Becquerel device, abbreviated Bq, is named radon remediation company after owner Henri Becquerel. The recommended radon degree dimension device is Becquerels per cubic meter, Bq/m3.
Should I buy a house with radon?
A radon mitigation system costs between $733 and $1,490 on average with most homeowners spending about $1,112. Depending on the home's design and foundation size, a complex radon reduction system can cost $2,500 or more. Professional radon level testing costs $150 per inspection on average.

If it's been a while because the last examination, even if the degree was low, think about having a new test done.
