There are many ways to detect (monitor) and record radon levels in a property. Two of the most cost-effective and easily usable types of radon detector are passive radon detectors and electronic radon monitors.
Passive detection provides a standardised result on printed paper. It is used for completing standardised tests for radon in properties in the UK. Passive detectors do not have a readable display, and need to be sent to a laboratory for analysis and results, so results can be delayed by weeks at times. A passive radon detector can be placed for periods from 7 days up to 1 year, but usually they are placed for a minimum of 3 months to reduce errors and allow an annual average calculation to be applied.
At 7 days a broad picture of radon levels can be achieved with a result reflecting a low, medium or high radon prognosis, as statistically there is a large variation around the mean (50%). At 1 month the reading could be considered a realistic reflection of radon levels at the time of measurement. However, it is recommended that a radon detector be placed for the standard measurement period of three months to obtain standard, comparable results for a property owners records, which will be seasonally corrected (annual averaging).
Detectors are normally placed in strategic locations to obtain averaged results. For example, in a house, two detectors will be placed, one in a living room and one in a bedroom. The detectors are analysed at a laboratory and results are sent to the property owner, with an averaged result calculated from the two sets of raw data. UK Radon Ltd can supply radon detectors, with a results analysis, at competitive rates.
