Home radon test workspace
Radon test planner
Run a test you can trust.
Choose the right test, place it correctly, record what happened, and check the procedure before you rely on the number.
No account required. Your unfinished record stays in this browser.
Before the result
The number is useful only when the test conditions make sense.
A county average cannot validate your device, room, timing, or closed-house conditions. This workspace records those facts first.
- 01 · Method
- Short-term, long-term, or continuous
- 02 · Placement
- Level, room, height, and interference
- 03 · Conditions
- Duration, doors, windows, and disruptions
One question at a time
From unopened kit to a usable record.
The planner adapts to whether you are preparing, currently testing, or checking a completed test.
- 01
Name the testing situation
First test, property transaction, or post-mitigation check.
- 02
Set the procedure
Record device type, placement, dates, and test conditions.
- 03
Check what may affect validity
See what is consistent, what is uncertain, and what should be checked against the device instructions.
- 04
Keep the evidence
Print a clear record of the procedure, result, limitations, and source links.
A procedural check, not a diagnosis
Official guidance stays attached to the answer.
State and device instructions can be more specific than general national guidance. RadonVerdict shows the source and tells you when to defer to those instructions.
Already have a mitigation system?
Check the indicator, noise, maintenance, or fan age.
