Test Type

Long-Term Radon Testing

Long-term testing runs across a longer period and gives a reading that better reflects seasonal variation. It is often a useful follow-up to a short-term test when the goal is a more representative picture of typical exposure.

Who this is for

  • Homeowners who are not working within a transaction timeline
  • Owners following up on a short-term result
  • People who want a reading that reflects seasonal variation

When it may be appropriate

  • When timing is flexible and a more representative reading is desired
  • After a short-term test suggests further evaluation would be useful
  • For a periodic check on a home you have owned for a long time

How the process works

  1. 1
    Place the long-term device
    The device is placed in a suitable lower-level location for an extended period.
  2. 2
    Continue normal living
    Long-term testing does not require closed-house conditions the way short-term testing does.
  3. 3
    Retrieve and report
    The device is retrieved at the end of the period and the reading is shared with an explanation.

What to expect

  • A reading that better represents typical conditions over time
  • Clear expectations about the timeline before results arrive
