Variability of indoor radon concentration in UK homes

This study investigated the variability of indoor radon concentrations in 518 100 homes in the UK.
The statistical analysis included measurements in 395 720 homes with downstairs living rooms and
upstairs bedrooms. The radon concentration in these bedrooms was found to be on average 63% of the
living room value. The analysis of 122 380 homes with living rooms and bedrooms situated on the same
floor found that there is a small difference in radon concentration of 9% between the two rooms. The
results showed that the ratios of the living room to bedroom radon concentrations were approximately
lognormally distributed. The geometric mean of the ratio was found to be 1.6 for rooms situated on
different storeys and 1.1 for rooms situated on the same floor. It was found that house
characteristics and energy efficiency measures affect the distribution of radon within homes.
Detached houses and those with suspended floors had higher radon levels in their upstairs bedroom,
66.7% and 76.9%...
