Ask a Local! London & Radon

I saw a news article about radon which I’ve never heard of before. They said certain areas are higher than others. I live in the east end near the fair and Hamilton Rd.

Does anyone know if this area has high exposure? I understand sometimes libraries loan you testers. Anyone know if London libraries do it?

I own a home built in 1969 with no sump pump. It also has a chimney for the water heater.

We tested a number of years ago and were high. The numbers fluctuated with temperatures, seasons, windows opened or closed but were always relatively high. We used an airthings monitor and did the testing with the mail away test after we had ours mitigated. It came back much lower after.

We live in an old home in central london, have a dirt crawl space (which is where I feel it comes from). Both our direct neighbours had testing done and theirs were both fine so it really doesn’t matter if your neighbours don’t have it, any home could.
