Usually above 4.0 is normally the standard for real estate, etc in the United States but in Canada it's higher. There's a great deal of great details on the EPA site and your regional health and wellness division ought to provide some technological support.

Radon's much heavier than air, so it seeps via basement walls out of the stone in the ground or whatever and gathers there. remediation contains mounting devices that continuously sucks air out of the basement or foundation and impacts it outside, producing a vacuum cleaner down there that pulls the clean air upstairs down.
It is estimated that two-thirds of all homes in the United States surpass the suggested Nashville Radon Removal Services action degree. It is also assumed that reducing levels to sub-4.0 p/Ci would cut annual cancer fatalities from radon in fifty percent. The ordinary international outdoor radon level varies between 5-15 Bq/m3, equal to 0.135-0.405 pCi/L. For every 99.9 Bq/m3, or every 2.7 pCI/L increase in long term radon direct exposure, lung cancer cells threat climbs 16 percent. Things to remember is that the reduced the level, the lower the risk.
What should you not do during a radon test?
Radon levels can vary by season, with the highest levels typically occurring during the months that we heat our homes.

Despite the fact that short-term tests are hassle-free, they do not tell the entire tale. Radon degrees normally rise and fall, so it's finest to have as lots of data factors that can be averaged out. When tested in laboratory researches, lots of radon test kits have actually likewise be found to be imprecise by as much as 25%.
How long does it take to get a radon test results back?
Radon tests can have two types of error: “False positive” – the test result is above 4 pCi/L although the long-term average is below it. The homeowner may “waste money” on a radon mitigation system. “False negative” – the test result is below the Action Level but the long-term radon level is above it.
Your house has a rather raised radon level above the UNITED STATE EPA's "Activity Restriction" of 4 pCi/L as disclosed by the two year-long measurements.
