Finding F-0632

“The daily averaged radon concentrations varied from 37 to 573 Bq/m3 for 10 selected workrooms, while hourly averaged radon measurements showed extreme variations from 6 to 1603 Bq/m3 due to radon fluctuations.”

Structure

Factor: Radon
Population: office workers
Setting: basement workroom, RS
Study design: case study of radon in workrooms of a thermally retrofitted public building in Serbia: one-month continuous measurement with a digital detector in 10 workrooms during the 2018/19 heating season and charcoal canister measurements in all basement workrooms in spring 2021, grouped by flooring type (class 4)
Effect: other 37
Averaging time: daily averages over one month, heating season 2018/19
Caveat: the sentence gives ranges; the daily ends are recorded as two rows and the hourly range sits in extra
