Once your radon sampler is sealed in the return mailer envelope, you should ship your kit as soon as possible. Tests are time sensitive:
- Short Term tests must arrive in the lab within 10 days of the stop date for a valid reading. After 10 days, results cannot be guaranteed.
- For Long Term tests, tests much arrive in the lab within 30 days of the stop date.
- For Radon in Water tests, the sample must arrive in the lab within 8 days of the stop date (4 if testing in Connecticut) .
Most tests do not include prepaid return shipping. Refer to your instructions to determine if your test includes return shipping. If you still need help, you can register your test online. The online registration system will inform you if your test includes prepaid return shipping, and if so, will provide instructions on how to use the return shipping.
We strongly recommend a shipping service that includes tracking to ensure delivery to our labs – UPS, FedEx, or USPS Priority Mail or better are all good options.
