INVESTIGATION OF RADON VOLUMETRIC ACTIVITY OF THE INTERIOR APARTMENT AIR IN RIVNE
Journal Title: Вісник Кременчуцького національного університету імені Михайла Остроградського - Year 2017, Vol 1, Issue 104
Abstract
Purpose. To investigate radon volumetric activity of the interior apartment air in Rivne. Methodology. Measuring of radon volumetric activity has been implemenedt in 600 apartments of the ground floors, semi-basements and base-ment apartments of Rivne housing and industrial space in the years from 2015 till 2017 with the help of "Alfarad Plus" radonometer within 24 hours for every apartment with further medium. Results. Average geometric value of Radon-222 volumetric activity in the apartments under investigation made up 200 Bk/m3 with geometric standard error 0,7865, average arithmetical value of radon volumetric activity in the air of the same apartments made up 262,5 Bk/m3 with standard error 194,4 Bk/m3. Average annual dose of irradiation formed in the process of radon and subsidiary products of its dissolution inhaled by inhabitants living on the ground floors of the houses makes up from 3,4 to 6,36 m3v accord-ing to different valuation under average geometric values of volumetric activity. The value of equivalently balanced radon volumetric activity exceed the rate of radioactive safety in houses where the given value makes up 100 Bk/m3 – in 21 per sent, and 200 Bk/m3 in 2 per sent apartments. Originality. Investigation and appropriate calculations have been made in Rivne for the first time. Practical value. The dimensions of radon field interior apartment of the ground floors, semi-basements and basement apartment of housing and industrial space in Rivne have been defined.
