Radon Testing

Radon in Air Testing

Radon-Air Testing is recommended every 1 to 3 years.

  • The EPA, the Surgeon General, and the American Lung Association recommend that all homes below the 3rd level be tested for radon gas since long-term exposure to radon gas is the second leading cause of lung cancer.
  • The average outside radon in air level is 0.4 picocuries per liter (pCi/L) and the average indoor level is 1.3 pCi/L.
  • In a Vermont residence there is a 1 in 8, chance that the radon in air level is at or above the EPA action level of 4.0 pCi/L. In New Hampshire there is a 30%, or approximately 1 in 3, chance of having an elevated level in the home.
  • The average mitigation cost to reduce radon in air levels is between $800 – $2,500.
  • Radon in air levels constantly fluctuate. It is prudent to follow-up a screening test with a year-long alpha track test (the most accurate radon test to obtain a yearly average).

Radon in Water Testing

Why should I test for Radon in my water:

  • Radon in water contributes to the radon in air level.
  • For every 10,000 pCi/L of radon in the water supply, the radon in air concentration is increased by 1 pCi/L.
  • Long-term ingestion of elevated levels of radon in water can cause cancer in the stomach and other internal organs.
  • The EPA proposed action level for private water supplies is 4,000 pCi/L (which the Vermont Department of Health defers to).
  • The New Hampshire Department of Health and Human Services has established 10,000 pCi/L as the action level for private water supplies.
  • Mitigation costs to reduce radon in water can run in excess of $5,000.
