What this sheet is for
Keep every radon test on one home together, so a follow-up is compared like with like. Each line also says why the test was done and what was decided after it.
Who it is for
Homeowners, tenants and landlords testing a home for radon, and anyone keeping the results for a sale or a mitigation quote.
How to use it
- Write the reference level your authority uses, its unit and who set it in the boxes at the top.
- Give each detector a number and fill its line as it goes out: kit, lab, room, height and start time.
- When it comes back in, write the end time, whether the house was kept closed, and the result exactly as the lab reports it.
- Note why each test was done and what you decided after it.
- Tick the list at the foot when something changes in the house, and test again.
What is on the sheet
One page, top to bottom:
Printed under the title: Every radon test on one home, in order: the kit, where it sat and for how long, the closed-house conditions and the lab's result, so a follow-up is read against the test it checks.
The level is your authority's. No reference or action level is printed: your health or radiation authority sets it, and it differs between countries. Follow each kit's own instructions, and put a follow-up test in the same room at the same height as the first.
Write-on lines: Property · Lowest lived-in level · Floor and foundation · Reference level · Unit · Set by · Mitigation fitted
Tests — one line per detector
Table, 8 rows: No. · Kit · Lab or device · Room · Height · Started · Ended · Closed · Result · Reason · Next step
Test again after — tick any that have happened since the last test
- Building work on the lowest floor or foundations
- New heating, cooling or ventilation system
- Windows or doors replaced, or draughts sealed
- A lower room brought into everyday use
- A mitigation system fitted, altered or switched off
- Moving in, or a long gap since the last test
Questions
Why is no radon level printed on the sheet?
Because the reference or action level is set by your health or radiation authority, it is not the same in every country, and some give it in a different unit. Write the level that applies to you at the top, with who set it, and read each result against that.
What makes a follow-up test comparable with the first?
The same room and the same height, the same closed-house conditions, and a kit of the type the follow-up calls for. The room, height and closed columns sit side by side so that shows at a glance; the kit's own instructions say how to run it.
