Improving the uncertainty on short-term radon measurements using PADC detector.

Radon measurements over a short-term period of a few days have proven a popular choice with the general public, despite the issue that the radon concentration can vary significantly over time and longer periods of integration are recommended. Performing short-term radon measurements using a Poly Allyl Diglycol Carbonate (PADC) detector would see a larger contribution from the statistical error associated with the measurements than for longer term measurements. This motivated the investigation to improve the uncertainty on short-term measurements by utilising a new formulation of high-sensitivity PADC and also by investigating the effect of increasing the scan area and extending the measurement time by just a few days.
