About

RadonLab is an independent editorial site about radon: what mitigation costs, how each system works, what testing measures and what the EPA Zones do and do not tell you. We are not a mitigation contractor, a testing lab or a lead broker — we do not sell your contact details to anyone.

What we publish

• Cost guides with the installed band, the source and the date it was checked.
• System guides that explain what a mitigation method physically does to soil gas.
• Testing guides that separate what a kit, a monitor and a professional measurement each prove.
• EPA Zone data with the zone definitions EPA actually uses, county by county.
• Comparisons decided on installed cost, running cost and service life.

How we work

• EPA publications, EIA price tables and state radon program pages before any secondary source.
• Ranges with their source and check date, never a single "average" posing as a quote.
• Estimates labelled as estimates, with the arithmetic shown.
• Errors corrected with the date noted; disagreements answered with documents.

Who writes it

The byline is RadonLab Editorial Team, edited byMara Kowalczyk. Every article lists its sources, and every cost figure names the publication it came from. When a reader sends a quote that contradicts a band, the band and the quote both go on the page.

What we do not do

We do not install systems, sell test kits or arrange quotes. We do not give medical advice. Radon is a health risk and the correct response to a high reading is a certified mitigator — our role is to explain the options, the numbers and the paperwork before you sign anything.
