By this study, it is focused to assessment of inhalation quality for Kocaeli province especially Northeast side of Marmara Sea (Gebze
county and its territory). In this case, radioactivity analysis in air was realized via air dose rate measurements around this region which
is so closed neighbor to big city Istanbul. By measuring of the outdoor gamma dose rates on 35 stations, it was possible to get the
average dose rate. Then it was calculated to annual dose in air. Besides, cancer risk was determined for Kocaeli. All these values were
compared with the World’s references (UNSCEAR) and reported finally. It was measured the average dose rate as 23.90 nGyhr-1
and
annual dose was calculated to 29.31 μSv. This dose is required to excess lifetime cancer risk as 1.02x10−4
. These values could be
compared to the similar studies which existed around the world. Finally, the average annual effective dose equivalent and excess
lifetime cancer risk for Kocaeli, are less than the world average. This study would be used to a reference for further investigations,
besides it will be usefull to compare with different studies for Kocaeli which, will be evaluated in the future, for example after a
nuclear pollution, such as based on a reactor leakage comes from Black Sea region and neighbours, nuclear attacks, etc., too. Another
benefit would be made to enlarge to find this kind of studies in literature.
