Radon Testing Cost in Georgia: What to Expect
Radon testing costs anywhere from $15 for a mail-in charcoal kit to $250 for a professional 48-hour continuous monitor test. The right price point depends on why you are testing: a routine screening, a real estate transaction, or verifying a mitigation system each call for a different tool.

DIY Kit vs. Professional Monitor: What the Price Buys
A $15 to $30 charcoal canister absorbs radon over 2 to 7 days and gets mailed to a lab. The price usually includes analysis and return shipping, and the result is a single average number with roughly plus or minus 25% accuracy. That is enough for a first screening or a routine follow-up in a home that has tested low before.
A professional continuous radon monitor (CRM) test at $125 to $250 is a different instrument entirely. The equipment itself costs $5,000 or more and is calibrated in a laboratory on a regular schedule. It records a reading every hour, logs temperature, humidity, and barometric pressure, and detects whether the device was moved during the test. Accuracy is roughly plus or minus 10%, and the report is the kind lenders, agents, and attorneys accept.
The gap matters most near the action level. A charcoal test reading 3.0 pCi/L could reflect an actual level anywhere from 2.25 to 3.75 pCi/L. The same home on a professional monitor showing 3.0 pCi/L sits between 2.7 and 3.3 pCi/L. When the decision riding on the number is a home purchase or a mitigation install, the narrower range is worth the difference in price.
What Drives the Price of a Professional Radon Test
Calibrated Equipment
Continuous radon monitors are professional instruments that require regular laboratory calibration. A meaningful part of the test fee covers maintaining, calibrating, and transporting that equipment to your home.
Test Duration and Trips
A standard test runs at least 48 hours and requires two visits: one to place the monitor following EPA placement protocols and one to retrieve it and pull the data. Longer test periods or multiple test locations in larger homes add to the price.
Real Estate Protocols
Transaction testing follows stricter rules: closed-house conditions, tamper monitoring, and documentation that stands up if the result is disputed. Tests tied to a purchase contract often sit at the higher end of the $125 to $250 range.
Reporting
You receive a written report with an hourly graph, the calculated average, and the environmental conditions logged during the test. That documentation is what makes the result usable in negotiations and closings.

Standalone Test or Part of a Home Inspection?
Radon testing is not included in a standard home inspection. Inspectors offer it as an add-on, usually $100 to $200 on top of the inspection fee. That can be convenient during a purchase, but ask what equipment the inspector uses. Some deploy professional CRM devices while others set out charcoal canisters, and the difference in data quality is significant when a repair negotiation may hinge on the result.
A standalone test from a radon company runs $125 to $250 and uses CRM equipment as a matter of course. It is the better fit when the inspection window has passed, when a previous result was borderline, or when you want the test and any follow-up mitigation quote handled by the same company.
How Often You Should Budget for Testing
Radon testing is not a one-time expense, but the recurring cost is small. The EPA recommends retesting every two years, after major renovations that change airflow or foundation openings, and whenever a home changes hands. For routine two-year checks in a home that previously tested low, a $15 to $30 DIY kit is a reasonable choice.
Homes with a mitigation system should verify performance with periodic testing, typically $100 to $200 for a professional verification test. Some homeowners add a consumer electronic monitor ($100 to $200 one time) for continuous awareness between formal tests.
If a test does come back at 4 pCi/L or higher, mitigation is the next step. Most systems in Georgia fall between $1,000 and $3,500 depending on foundation type. Our radon mitigation cost calculator gives you a foundation-specific estimate, and you can check radon levels by zip code to see how your area trends before you test.
