Impact of temporal variability of radon concentration in workplaces on the actual radon exposure during working hours

Abstract For workplaces where significant diurnal variations in radon concentrations are likely, measurements to evaluate average radon concentration during working hours could be useful for planning an optimized protection of workers according to the 2013/59/Euratom Directive. However, very few stu...
