What are picocuries?
A picocurie is one trillionth of a curie. To put the relative size of one trillionth into perspective, consider that if the Earth were reduced to one trillionth of its diameter, the “picoEarth” would be smaller in diameter than a speck of dust.
Is .4 radon safe?
FAQs: Acceptable Radon Levels. What constitutes an acceptable or safe radon level? According to the EPA, the maximum “acceptable” level of radon is 4.0 pCi/L, but even that level is not “safe”, per se. The EPA strongly recommends you consider radon mitigation between levels 2.0 and 4.0.
Is 5 a high radon level?
Fix the home if the radon level is 4 picocuries per liter (pCi/L) or higher. Radon levels less than 4 pCi/L still pose a risk and, in many cases, may be reduced. Take steps to prevent device interference when conducting a radon test. EPA estimates that radon causes thousands of cancer deaths in the U.S. each year.
What level of radon is unsafe?
4 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. The EPA estimates that a radon removal system costs about $1,200 for an average house.
How many Sieverts are in a becquerel?

What are picocuries per liter?
A picocurie per liter measures how many picocuries of radon can be found in one liter of air. A curie is a measurement of radioactivity. Each picocurie is a trillionth of one curie.
Is it OK to live in a house with radon?
Radon is the second leading cause of lung cancer after cigarette smoking. If you smoke and live in a home with high radon levels, you increase your risk of developing lung cancer. Having your home tested is the only effective way to determine whether you and your family are at risk of high radon exposure.
Should I walk away from a house with radon?
Radon-related deaths are due to exposure over the course of a lifetime. “You should definitely take it seriously but you really don’t need to walk away from the home. It’s actually pretty easy to remove radon, and it’s not that expensive,” Consumer Reports Home Editor Paul Hope said.
What time of year is radon highest?
winter
To answer that question, yes, radon levels in a home tend to be higher during the winter. And those higher levels of radon gas can lead to an increased chance of lung cancer. While indoor radon gas levels are generally higher during winter, sometimes the summer can have higher indoor radon levels.
Where can I find Sieverts?
The equivalent dose (expressed in sieverts) is obtained by multiplying the absorbed doses of individual tissues and organs by their respective radiation weighting factors (WR) for taking into account the types of radiation.
How many Picocuries are in a microcurie?
