Radon testing is a very simple process for the householder. The RPII service costs 40, can be handled by post and does not involve a visit by a specialist.
The homeowner sends in an application by post or over the Internet and receives by post two small plastic detectors about the size of a golf ball cut in half. One is placed in a living area and the other in a bedroom.
Radon levels can vary from day to day based on weather and ventilation, so the detectors are left in place for three months. This evens out variations to provide a good average measurement of radon over time.
The detectors are posted back to the RPII, where they are opened and examined.
The householder then receives a radon report indicating whether their home exceeds the 200 Bq per cubic metre action level, above which the RPII recommends remedial works to lower radon concentrations.
Private companies also provide testing services and can be contracted to do remedial work. In most cases simple ventilation is enough to remove excess radon from subfloors and spaces under buildings, where it can collect.
