Monitoring Radionuclides in the Atmosphere over the Czech Republic after the Fukushima Nuclear Power Plant Accident

Popis výsledku v původním jazyce

This paper presents the results of atmospheric radioactivity monitoring over the Czech Republic, as obtained by the Radiation Monitoring Network, following the Fukushima Dai-Ichi Nuclear Power Plant accident. Maximum values for 131I were 5.6 mBq/m3 in aerosol form and 13 mBq/m3 in gaseous form. The maximum values for 134Cs and 137Cs were 0.64 and 0.72 mBq/m3, respectively. The estimated effective half-time for removing the activity from the atmosphere was 6–7 d and 3.5 d for caesium and iodine, respectively. The gaseous-to-total activity ratios of 131I ranged between 0.3 and 0.9, with an arithmetic mean value of 0.77. The mean value for the 134Cs/137Cs ratios was close to 1.0. The effective inhalation dose due to the accident for an adult living in the Czech Republic was estimated at <0.00004 mSv, out of which the proportion of 131I was 88 %.
