Radon in Air

   Basic Profile

Aquatek has been providing quality radon analysis for over 20 years. We provide short term tests for radon screening that come in both single and dual test kits. Testing is recommended for real estate transactions, after house renovations and to test that installed mitigation systems are operating correctly.

  • Short-term single charcoal canisters are ideally suited for homeowners who want a quick, accurate and inexpensive way to estimate the radon level in their home. The method is EPA approved and the on-site exposure process is easily performed by the homeowner.
  • Short-term dual device measurements are ideally suited for time-sensitive situations such as real estate transactions. Side-by-side dual short term tests provide the best combination of speed and accuracy upon which real estate transactions may be based.

Health Effects

Radon breaks down naturally and forms radioactive decay products. When the air is inhaled, the radon decay products can become trapped in the lungs. As these decay products break down further, they release small bursts of energy which can damage lung tissue and lead to lung cancer.

Scientists estimate that radon exposure causes many thousands of lung cancer deaths in the United States each year. The risk of developing lung cancer from radon depends upon the concentration of radon and the length of exposure. The risk of lung cancer is especially high for smokers with homes having elevated radon levels.

Source

Radon is a radioactive gas which occurs in nature as a result of the radioactive decay of uranium. Uranium is a radioactive element found in rocks and dirt deep beneath houses and buildings. As the Uranium breaks down it decays into radon. The radon then moves through small spaces in the soil and rock on which a house is built. When radon is present it can seep into a home through dirt floors, cracks in concrete floors and walls, floor drains, sumps, joints, and tiny cracks or pores in hollow-block walls. Radon is always highest in its highest concentration in the lowest floors of a building.

Results

If the initial measurement result is less than 4 pCi/L, there is a relatively low probability that mitigation is warranted. If your initial short-term screening measurement result is 4 pCi/L or higher, you should conduct a follow-up short-term measurement before proceeding with mitigation. The follow-up test should be conducted in the same location as the first, and should be conducted under closed-house conditions. Results of the initial and follow-up test results should be averaged together. If the resulting average value is equal to or greater than 4 pCi/L, radon mitigation is recommended.

If your air radon level is elevated and your home has a water well, it is also advisable to have your water tested for radon. Wells with high levels of dissolved radon can release radon gas into the air when water is drawn from the supply lines and contribute significantly to the total gas concentration in the air.
