Radon Gas is a radioactive gas that rises up through the earth. In higher concentrations, over time it increases the occupant’s risk of lung cancer. It is the leading cause of lung cancer among non-smokers in the US. It is a byproduct of decomposing uranium.
In Rhode Island, radon testing is licensed and regulated through the Department of Health. You should use a RI Licensed Radon Measurement company, like us. I’m licensed to test for radon. A DIY test kit will likely come into question during negotiations.
Although generally speaking, yes, but in Rhode Island, 1 of 5 houses tests above the EPA threshold of 4.0pCi/L. As a matter of fact, I tested 2 homes next door, within the same week, one tested at 22.1 pCi/L, the other tested at 1.2 pCi/L. The only way to know is to have your home tested by a licensed professional.
There are many ways, but I use a continuous radon monitor (CRM). This is a machine that stays in the home for a 48 hour minimum testing period, and takes a reading every hour for the duration of the test. It then produces data and an average radon level. This average is the result that is used to determine if the home needs to be fixed.
Any home can have radon gas levels above the EPA action level. This includes homes with basements, on slab, crawlspaces, dirt floor, concrete floor, new homes and old homes.
Possibly, but I’ve tested brand new homes with high radon levels. Radon particles are small and are pushed/pulled into the home by pressure differences.
My machines have anti tamper features, I will know if the machine has been moved, bumped, or had the power interrupted. It also has a battery back-up capable of the 48 hour test if power is lost.
I leave documentation with the occupants explaining the need for proper testing conditions. In some cases, opened windows can cause low pressure in the home and draw more radon gas into the home, educating all parties is the best way to get an accurate result.
There are effective remediation systems that typically cost about $1000 to have installed. These systems can reduce the radon gas levels below the EPA action threshold in almost every case.
My machines are calibrated annually by the manufacturer. There are also regular performance checks done by a different lab to ensure the machine is working and I’m properly reading the results.
Yes, I carry the appropriate licenses to give you the radon gas test for periodic testing you require for your daycare center.
