“…The Japanese National Tourism Organization (JNTO) reports air dose rates about 0.037 μSv·h –1 for Tokyo City . In comparison to current air dose rates from selected previous Olympic sites (Figure , Table S2), all previous Olympic sites show on average a same or higher air dose rate ranging from 0.072 μSv·h –1 in Beijing (China) to 0.135 μSv·h –1 in Helsinki (Finland) − or even 0.153 μSv·h –1 for Cape Town (South Africa), where the Soccer World Cup took place in 2010 …”

We conducted a comprehensive radiation hazard assessment of the Tokyo Olympic Games (Tokyo 2020, postponed to 2021). Our combined experimental and literature study focused on both external and internal exposure to ionizing radiation for athletes and visitors of the Games. The effective dose for a visit of 2 weeks ranges from 57 to 310 μSv (including flight dose). The main contributors to the dose are cosmic radiation during the flights (approximately 10–81%), inhalation of natural radon (approximately 9–47%), and external exposure (approximately 8–42%). In this complex exposure, anthropogenic radionuclides from the Fukushima nuclear accident (2011) always play a minor role and have not caused a significant increase of the radiological risk compared to pre-Fukushima Japan. Significantly elevated air dose rates were not measured at any of the Tokyo Olympic venues. The average air dose rates at the Tokyo 2020 sites were below the average air dose rates at the sites of previous Olympic Games. The level of radiological safety of foods and water is very high in Japan, even for athletes with increased water and caloric demands, respectively.

“…By the way, there are also stated worldwide studies in the literature. For example, Licínio MV and friends have evaluated in 2013 for Brazil (15). Another study by Ghiassi-Nejad and Mortavazi in 2002 indicates the absorbed dose rates in air (ADRA) values concerning the Ramsar region of Persia.…”

Radioactivity measurements for water, soil, and air have been completed in national and international regions. The radioactivity process is randomized and occurs naturally by primordial nuclides. Another case is hand-made reactions which realized by artificial reactions. The high rate of the total dose of radiation, whichever is exposed to humans, originates as Natural Radioactivity. In this case, environmental radioactivity measurements are important to investigate the background radiation level, especially for primordial radioactive sources. This radiation which measured outdoor gamma dose includes both cosmic rays and terrestrial elements. Terrestrial radiation can be measured via gamma-ray spectroscopy separately. By the way, cosmic effects would be calculated by subtracting terrestrial from measured outdoor gamma dose. Scientific Committee (UNSCEAR, 2000) declares the annual dose for humans as 2.4 mSv. The radionuclides present in soil samples (terrestrial components) are considered responsible for a portion of this amount (1). Rest amounts are originated water (2) and air, too.

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.
