Short-term test protocol
How to test a home in Bernalillo County
Use a short-term radon test on the lowest level that could be regularly occupied. Keep windows and exterior doors closed under the kit instructions, place the device away from drafts, heat, humidity, and exterior walls, and do not move it during the test.
-
1. Choose the level
Test the lowest occupiable floor
Use a basement family room, bedroom, office, or the first floor when the basement is not suitable for regular occupancy.
-
2. Stabilize the house
Follow closed-house conditions
Follow the device instructions before and during a short-term test. Avoid unusual ventilation that can distort the reading.
-
3. Place it correctly
Keep the device in normal room air
Keep it away from windows, exterior doors, fans, direct heat, high humidity, and places where it can be disturbed.
-
4. Preserve the result
Record dates, location, and pCi/L
Keep the report with the exact room and test period. Those details matter when comparing a follow-up test, a real-estate test, or a mitigation quote.

Result to decision
What to do after the test
Under 2.0 pCi/L
Keep the result and retest on a sensible schedule or after major building changes.
2.0–3.9 pCi/L
Use a follow-up or long-term test to reduce uncertainty before making a large spending decision.
4.0+ pCi/L
Confirm as directed, then move into mitigation scope and local cost planning instead of repeatedly delaying the decision.
Retest trigger: a 2.0-3.9 pCi/L home result should be confirmed here because 3.4 pCi/L average, 2.1 pCi/L median, and 24.3% of reported tests at or above 4.0 keeps the county from being a dismiss-it signal.
Keep each question on the right page
Testing gives you the number. The official local record gives it context.
Do not use a county average as a home result, and do not start with contractor prices when the property has not been tested. Move through the sequence once: test, interpret, then compare written quotes only if the result supports it.
