01 / Start early
Make the result part of your move-in decision
Start by identifying when a radon result would help you make a decision: before an inspection deadline, before signing a lease, or before bringing furniture into the home. Radon is a radioactive gas that cannot be detected by sight, smell, or taste; exposure increases lung cancer risk. Florida Department of Health guidance says neighborhood measurements cannot predict an individual home's level. A nearby property's report therefore cannot replace testing the home you intend to occupy, even when the buildings look similar.
Ask the seller or landlord for existing test reports and any radon-reduction records while you arrange access. Florida health officials have documented elevated radon in different building types, including high-rise condominiums, so an upper-floor address alone should not end the discussion. Use early testing to preserve time for questions and corrective work. If your move is already imminent, contact a Florida-certified measurement business about the earliest valid testing window and report delivery, then put the follow-up decision on your calendar.
Action checklist
- Identify the date by which you need a usable report.
- Request previous measurements and mitigation records.
- Confirm who can authorize access before occupancy.
02 / Review records
Check what an earlier report actually measured
An earlier result may be useful, but review the complete report rather than accepting a verbal statement that the property passed. EPA's homebuyer guidance advises examining how testing was performed, where the device was placed, and whether relevant changes have occurred. Match the address and tested space to your intended home. Ask which floor and room were measured, when the test began and ended, and whether the report identifies the testing method. Keep the report itself in your move-planning folder.
Explain how you intend to use the home, especially if you will occupy a lower level that was not previously tested. Ask about renovations or changes to heating and cooling since the measurement, and request clarification when testing conditions are undocumented. A newly built home with radon-resistant features still needs testing; Florida's buyer guide recommends testing such homes as soon as possible after occupancy. Treat construction features and old measurements as information to review with the tester, rather than a permanent assurance about future levels.
Action checklist
- Match the report to the property and intended living space.
- Ask about building changes since the test.
- Request a new measurement when the earlier report leaves material questions.
03 / Choose a test
Match the testing method to your available time
Short-term testing suits a decision that must be made soon, while a long-term measurement provides a better picture of the home's year-round average. EPA describes short-term tests as lasting two to 90 days, depending on the device, and long-term tests as lasting more than 90 days. These are measurement periods, not promises about report delivery. For a kit sent to a laboratory, also allow for return shipping and processing. Ask the provider to distinguish device exposure time from the date you will receive the written result.
For a fast real estate decision, Florida's buyer guide describes two simultaneous passive tests in the same location for at least 48 hours, or a continuous-monitor test lasting at least 48 hours. Some devices require longer exposure. Have the measurement business explain which protocol it proposes and how the result will be interpreted. If you choose a kit for your own household screening, follow its laboratory instructions and arrange any recommended confirmation. A long-term test can be valuable after occupancy, but cannot answer a deadline only days away.
04 / Verify providers
Check Florida certification before booking paid testing
Florida requires state certification for businesses charging for radon testing. The Department of Health also explains that certified individuals must work through or associate with a certified business. When requesting service, obtain the business name and certification number, plus the name and certification details of the person performing the measurement. Check current status through the state's certification resources; its service page specifically warns readers to check expiration. A general home-inspection credential should not substitute for verifying the radon credentials relevant to the service you are buying.
Compare the proposed work before comparing quotes. Ask what device will be used, who places and retrieves it, what testing instructions occupants receive, and when the report will arrive. Ask whether a repeat measurement is included if the original test cannot be used, and how additional visits are billed. Florida permits occupants to test without certification under its stated exemption, but a buyer seeking access before ownership should discuss the arrangement with the owner and measurement business. Keep written booking terms alongside your inspection or lease documents.
Action checklist
- Verify the measurement business and individual through Florida resources.
- Confirm the report deadline in writing.
- Ask about repeat-test terms and all quoted charges.
05 / Protect conditions
Reserve a testing window away from move-day traffic
Choose a period when everyone with access can follow the testing instructions. Florida's buyer guide calls for closed-house conditions for at least 12 hours before a short-term test lasting two to seven days and throughout that test. Windows stay closed, and exterior doors open only for normal entry and exit. Repeated furniture deliveries, painting with open windows, or a long unloading session make coordination difficult. As a planning choice, reserve the measurement window before those activities or after they finish, with the required preparation period included.
Keep heating and cooling operating as instructed rather than changing the home's ventilation to influence the reading. EPA's transaction guide distinguishes equipment bringing outdoor air inside from normal recirculating operation, and allows a radon-reduction fan to continue running. Give the tester details about your equipment and follow the applicable protocol. Share written instructions with the seller, landlord, cleaners, contractors, and anyone else entering. If a window is opened, equipment stops, or a device is disturbed, tell the tester so the report's validity can be assessed.
Action checklist
- Block out preparation, measurement, and retrieval on the shared schedule.
- Keep delivery and renovation appointments outside the testing window.
- Record interruptions and report them to the measurement provider.
06 / Read the result
Identify the next action before closing the task
Read the reported concentration, units, testing method, and any qualifications together. EPA recommends reducing radon when the home's level is 4 picocuries per liter, written as pCi/L, or higher; it also recommends considering reduction between 2 and 4 pCi/L because no safe exposure level is known. A result below 4 should therefore not be described as a guarantee of safety. Ask the measurement professional to explain whether the completed protocol supports a mitigation decision or whether another measurement is needed.
Follow-up depends partly on how the first measurement was obtained. EPA's household testing guidance recommends confirmation after an initial short-term result of 4 pCi/L or higher, using a long-term test or another short-term test as appropriate. Its citizen guide recommends an immediate second short-term test when the first exceeds twice the action level. A properly completed transaction protocol may already involve paired tests or a continuous monitor. Ask which pathway applies before ordering another device, and assign someone responsibility for arranging and reviewing the next measurement.
07 / Coordinate repairs
Agree on responsibility and verify mitigation results
If reduction is recommended, contact a Florida-certified mitigation business and provide the measurement report. Request a written proposal describing the work, access needs, installation timing, operating instructions, warranty, and testing arrangements. Buyers should discuss responsibility and timing with the seller before relying on a repair promise. Renters should send the landlord the results in writing and request a plan for additional testing or reduction, as EPA's tenant guide recommends. Building alterations require coordination with the owner; a renter should not independently commission structural work without authorization.
Leave room in the schedule to verify the installed system. EPA's consumer guide recommends a post-mitigation test within 30 days of installation, beginning no sooner than 24 hours after the system is operating, with its fan on if applicable. It also recommends an independent follow-up measurement. Ask the contractor and measurement business to coordinate those appointments before installation starts. If the report will arrive after your planned occupancy date, discuss the timing with them and the property owner, and make an explicit household decision about temporary arrangements.
Action checklist
- Document who authorizes, pays for, and schedules the work.
- Book post-mitigation measurement before installation.
- Collect operating instructions, warranties, and the verification report.
08 / Complete the handoff
Keep a usable radon record after the move
Create a short handoff record that makes unfinished work visible. Include the property address, tested room, measurement dates, provider details, result, and agreed next action. Attach the original reports and any system documents rather than reducing everything to a pass-or-fail note. For a rental, retain the written exchange with the landlord and the date you expect a response or appointment. For a purchase, keep the relevant agreement with the inspection records so responsibility for an outstanding test or repair remains clear after keys change hands.
After occupancy, review the plan against how you actually use the home. A room intended for storage may become an office or bedroom, and planned renovations may change the building. EPA's homebuyer guide advises testing before and after projects that convert lower-level space to living space. Ask your measurement provider what future testing fits the property and any installed reduction system. Put agreed reminders on the household calendar, keep system instructions accessible, and close the move-in task only when the report has been reviewed and any follow-up has an owner.
Action checklist
- Save complete reports and written agreements in one folder.
- Assign responsibility for every outstanding appointment.
- Calendar follow-up measurements and system maintenance instructions.

Reader questions
Questions about this topic
Can I complete a radon test on moving day?
Repeated unloading and open doors can conflict with short-term testing conditions. Reserve a separate window that includes preparation, device exposure, and retrieval.
Does a Florida condominium on an upper floor need consideration?
Yes. Florida health officials report elevated radon in high-rise condominiums. Ask about measurements for your intended unit rather than assuming its floor rules out elevated levels.
Can a renter test without hiring a business?
Florida's guidance permits occupants to test without certification. Follow the kit instructions, coordinate access and conditions, and share elevated results with the landlord in writing.
Does radon-resistant construction eliminate testing?
No. Florida's buyer guide recommends testing new homes with radon-resistant features as soon as possible after occupancy.
Is 48 hours the entire turnaround time?
No. It is a minimum measurement period for certain protocols. Preparation, appointments, shipping, laboratory processing, and report delivery can add time; confirm the full schedule.
