EPA recommends that testing device(s) be placed in the lowest level of the home suitable for occupancy. This means testing in the lowest level (such as a basement), which you could use for living space without major renovations. The test should be conducted in a room to be used regularly (like a family room, living room, playroom, den or bedroom); Do not test in a kitchen, bathroom, laundry room or hallway.
Radon Tests For Existing Homeowners
We offer do-it-yourself EPA approved charcoal canisters for homeowners. These devices can be mailed to you for only $35 including lab analysis. Simply expose the device in your home for 48 hours then seal and return to the lab. You will receive your results in about a week. Includes one 4” charcoal canister, instructions and pre-paid mailer.
Diagnostic Testing
Once high levels of radon or chemical vapors has been found in a property, to properly design a mitigation system, air pressure field diagnostics should be performed. Air pressure field diagnostics is a process of discovering the air pressure measurements under the slab of a building. To perform this type of diagnostic testing, R.E.I uses micro manometers to measure the air pressure. Most facilities will have some type of positive pressure, with air being forced up through the slab due to the natural stack effect, or HVAC system. Air pressure field diagnostics entails core drilling a suction point in the slab, and systematically drilling tiny test holes throughout the slab. Once the holes are drilled, a micro manometer is connected to each test hole to provide an air pressure reading. A fan unit is then connected to the cored pit, and turned on to see the field extension, or the achieved negative pressure measurement under the slab. The filed extension of the fan will determine the mitigation system design and quantity of systems needed to properly pull air under the entire slab of the building. The mitigation system design includes, quantity ofsystems needed, fan model, number of suction points in the slab, vent stack size, and routing of the PVC vent stack.
Radon Testing For Real Estate Transactions
For real estate transactions we recommend state-of-the-art electronic test devices called "Continuous Radon Monitors" or "CRMs”.
CRM devices continuously measure and record the amount of radon in the air on an hourly basis. This information will reveal any unusual or abnormal swings in the radon level during a test period and are specifically designed to deter and detect test interference or weather anomalies. Each device contains a motion detector to determine if the device has been moved. Results are available immediately at the conclusion of the test. Test prices start at $175 for a 48 hour test in the Indianapolis area.
