Abstract

Radiodine, 131I, is released into atmosphere during normal operation of the radiopharmaceutical pro-duction facility at the Karpov Institute of Physical Chemistry (NIFKhl) in Obninsk city. The paper presents analysis of monitoring of 131I concentration in the air and radiation dose to the population of the Obninsk and its surroundings. To estimate annual radiation doses to the public 131I concentration in the environment was first calculated. Data of radiation monitoring carried out in Obninsk were used to confirm the correctness of computed mean annual volume activity of 131I in the air. Annual radio-iodine doses to the public of Obninsk and its surroundings calculated exposed to radiation between 2015 and 2019 were within the range of 0.5 to 2.0 μSv/year, this level was considerably lower the limit set for the population living near the NIFKhI (300 μSv/year). The risk from radioiodine released into the atmosphere in the period from 2015-2019 was negligible (<10-6 year-1).

Key words
