Geographic focus

Local context begins—and ends—with the building.

This guide focuses on North Florida, but it does not rank towns or predict a home’s result from a map, ZIP code, age or appearance.

Planning maps

A zone is not a home result.

EPA developed its radon-zone map from regional measurement, geology, radioactivity, soil and foundation information. EPA also states that the map should not be used to determine whether individual homes need testing. That limit matters more than a neighborhood narrative: test the building.

Building-specific factors

Age, price and a slab label do not produce a number.

Construction and operating conditions affect how soil gas moves, but a generic description cannot reliably predict indoor radon. This site therefore does not claim that newer homes concentrate more radon, older homes leak more radon, air-conditioning inevitably raises radon or one North Florida soil type determines a household result.

Use the actual measurement and documented conditions. When a result is elevated, a qualified provider can assess the foundation and explain a design for that building.

Provider coverage

Statewide certification is not a scheduling promise.

The Florida Department of Health says certified businesses and individuals may provide services statewide. Each independent business still decides its present travel area, capacity and scheduling. Florida Radon Pros does not advertise a provider network or promise coverage, response times, reports, quotes or appointments.

Private wells

Test indoor air first; use the right test for water.

EPA says soil gas is the main cause of radon problems and that well water can sometimes contribute radon indoors. When indoor air is elevated and the home uses a private well, water can be evaluated with devices and procedures designed for water—not an air test. A location’s well prevalence should never be used to invent a radon result.
