United Inspection Service offers the AccuStar test kit for a Radon In Air test. Click on the Price navigation button for current pricing. The twin canister test kit is an EPA approved Radon Gas Test kit. This EPA refers to this as an ACAD test or Activated Charcoal Absorbtion Device. The inspector will place the canisters at the time of the inspection. United Inspection does NOT pick up test canisters. The buyer or real estate agent may pick up the canisters. The test is valid from 24 to 96 hours. EPA protocol and best accuracy is 48 hours.


What is radon?  Radon is a colorless, odorless and tasteless radioactive gas. Radon is created when naturally occurring elements such as uranium and radium in rocks and soil break down during a process called radioactive decay. Once radon is emitted, it migrates upwards to the ground surface through pore spaces in the soil. Radon can enter homes through cracks, joints, cavities and gaps in building floors and walls.
Radon gas decays into microscopic solid particles that enter the lungs when inhaled. The particles become trapped in the lungs and decay further, releasing small bursts of energy as they continue to break down. These bursts of energy damage lung tissue and can increase the risk of developing lung cancer over the long-term.

 

What are acceptable levels? The EPA action level is 4 picoCuries of radon per liter of air (4.0pCi/L). Readings below 4.0 are acceptable and readings above 4.0 are not.
