Radon Gas Levels by Zip Code
The Florida Health department has created a great database, linked here, of radon test results as reported by certified radon businesses and facilities per Florida Statute 404.056. This tool allows you to see the percentage of radon tests that returned greater than a 4 pCi/L result. The EPA recommends homes and properties be mitigated if the level of radon is above 4 pCi/L.
Below are some of the zip codes in Miami-Dade County over 10% that we were able to acquire. Last checked: October 10th 2022.
Percentage >= 4 pCi/l
Per the Florida Department of Health: This radon data does not represent a scientific or statistical survey; therefore, it should be interpreted with caution. The data provides an indication of the radon potential within a zip code if a large enough and properly distributed number of buildings have been tested and reported for the area. This data cannot be used to predict the radon level for existing or new construction. Structural features, construction details, and ventilation operations differ from building to building and greatly influence radon concentration. Structures within the same zip code may have dramatically different indoor radon levels due to these differences. Inferring indoor radon levels for untested buildings based on indoor radon data from tested buildings is not possible.
Building History in Miami, FL
The largest city in Florida, Miami boasts a sprawling metro area combining a vast downtown and extensive suburban network of neighborhoods. Though it is home to the University of Miami, the city is not just a college town. Miami is a major economic hub and a massive tourist destination hosting the busiest cruise port in the world and known as the location of internationally popular South Beach.
Miami's architecture is a stunning combination of contemporary high-rises, mansions, and historic bungalows. Often used building materials include stucco and concrete. As building codes in the area became stricter on storm proof building practices and consumers became more focused on energy efficiency and sealed structures, indoor air quality issues in this area sky rocketed due to the decreased rate of indoor/outdoor air exchange. Additionally, Miami sits in a Level 2 radon area denoting an elevated radon ground source as seen below. However, EnviroHome has found that the larger concern with indoor radon levels in Miami is in fact the radon from building material emanation.
Up until recently it was believed that there were only two sources of radon exposure – radon gas ground source seepage, and off-gassing of radon impacted groundwater. In the low ground source areas such as Miami, it was generally assumed that radon was not a major concern and not one that would warrant mandatory testing associated real estate transactions, etc. Today we are finding highly elevated radon levels in many Miami, FL concrete building structures. Radon tess results clearly show that the radon comes from the building materials and specifically from the poured concrete.
The problem is most significant in Miami condominium, apartments, and high-rise structures where large volumes of formed in-place concrete are used and where large concrete surface areas are present in close proximity to building occupants living in the individual units.
Our radon testing and radon mitigation system installation company specializes in radon emanating from building materials. We provide testing, diagnosis, and full scale plans to mitigate radon overseen by certified radon experts, licensed professional engineers, and licensed general contractors to ensure the radon levels in your property are at healthy levels.

If you still do not see your school the best course of action is to call the Radon and Indoor Air Program at 850-245-4288 or 800-543-8279 or email firstname.lastname@example.org
Maximum Radon level (pCi/L)
Average Radon Level (pCi/L)
Per the Florida Department of Health: Radon Testing is required for State licensed, regulated, owned or operated Facilities. This requirement is the same for all buildings in facilities required to be tested for radon per Florida Statue 404.056. Currently all buildings in a facility that are used by the clients of the facility are required to be tested twice, five years apart. Once tested twice, testing is no longer required unless one of the triggering events occurs:
1) a building is subject to significant structural renovation or a change in facility operation equivalent to a building structural change, or
2) the facility legally becomes a new facility. Examples of a legally new facility would be the issuance of a new license, or there could be a change in ownership or operator. If a facility operator failed to complete the required testing in any building by the time it was due, the testing should be completed as soon as is practical.
