Abstract
A method of monitoring radon in an area, comprising: acquiring a series of radon measurements for the area; obtaining a characteristic value relating to ventilation in the area; and calculating a weighted average from the series of radon measurements. Using a characteristic of the ventilation to calculate the weights allows some knowledge of the ventilation rate to be used in the averaging process so as to improve the quality of the averaged data. With a high ventilation rate, the radon level drops rapidly, with the removal of radon by ventilation dominating any radon source, and so an average can be more strongly weighted towards the current value. With a low ventilation rate, the removal of radon slows and so the noise in the data is taken into account. Combining the actual radon measurements with knowledge of the ventilation rate allows the averaging function to provide better time resolution.
