What this means for you
A small number of homes in moderate areas do exceed the action level, so a test is a sensible precaution — especially if you spend a lot of time on the ground floor or have a basement. At around £29 for a 3-month postal detector, it's inexpensive peace of mind.
Even though PO36 is in a moderate risk area, it's worth remembering that radon levels can vary from house to house — even between neighbours. If you'd like certainty, a simple postal test removes all doubt.
Seasonal factors
Radon levels tend to be higher in winter when homes are sealed up and ventilation is reduced. If you're planning a test, autumn or winter is the best time — your result will reflect a more realistic worst-case scenario. Summer tests may underestimate your true annual exposure, since open windows dilute indoor radon. The standard 90-day postal test is designed to average out daily fluctuations and give a reliable reading.
