Fission products from the damaged Fukushima reactor observed in Hungary

Abstract

show that the radiological impact of this event at Hungarian locations has been of no considerable concern.

Predictability of the dispersion of Fukushima-derived radionuclides and their homogenization in the atmosphere

“…Regional transport over Europe occurred within this high pressure system that remained stable until 25–26 March. Following the anticyclonic flow, the first observations and highest peak concentrations were reported in Northern and Eastern Europe with arrival times 21–24 March through Belgium, Germany, Denmark, Belarus, Poland and the Carpathian Basin 17 26 27 28 29 30 31 . By 23–26 March, the plume had been detected in entire Europe except in Southern Italy where a subtropical high pressure system blocked the dispersion until 27–30 March 24 27 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 .…”

“…This yields an average uncertainty of concentrations with a factor of 1.5 due to wet scavenging which is comparable to the uncertainty of the initial ratio of aerosol and gas forms. Atmospheric half-life of particulate 131 I was estimated to be 6 days (median) with a range between 3.25 and 8.5 days 28 29 . Figure 7 clearly shows that the uncertainties caused by deposition processes dominate over uncertainties of emission scenarios only after 20–25 March.…”

“…6 The FNPP accident resulted in the release of 137 Cs and 131 I causing the contamination of soil, plants, rivers, and ocean over 15 prefectures of Japan. [9][10][11][12][13][14][15][16][17][18][19][20] Radioactive MPs may possess a higher human risk than non-radioactive MPs by the inhalation and ingestion of MPs containing radionuclides.…”
