Radioiodine and radiocesium in Thessaloniki, Northern Greece due to the Fukushima nuclear accident

Monitoring rainwater and seaweed reveals the presence of 131I in southwest and central British Columbia, Canada following the Fukushima nuclear accident in Japan

“…Airborne 131 I was observed in Europe [4][5][6][7], the Canary Islands off the northwest coast of Africa [8], South Korea [9] and in the northwest United States [10]. Iodine-131 concentrations in rainwater of ≤3.5 Bq/L were reported in Milano, Italy [4], Bordeaux, France [6], and Jeju, South Iodine-131 content in rainwater and seaweed was monitored following the analysis of gamma-ray decay spectra acquired using a shielded high purity germanium (HPGe) detector.…”

Radioactivity concentrations of 131I, 134Cs and 137Cs in river water in the Greater Tokyo Metropolitan area after the Fukushima Daiichi Nuclear Power Plant Accident

“…The contamination affected not only the areas around the reactor site itself, but also a relatively large area of eastern mainland Japan, with some specific areas becoming heavily contaminated (e.g., Yoshida and Takahashi, 2012). In addition, a small amount of the radioactive material became airborne and was dispersed into the atmosphere (Manolopoulou et al, 2011;Pittauerová et al, 2011;Leon et al, 2011;Bolsunovsky and Dementyev, 2011) and in the oceans (Honda et al, 2012), spreading all over the world. lower than the provisional regulation value (300 Bq/kg) guided by the Ministry of Health, Labor, and Welfare but was above the provisional regulation value for infants (100 Bq/kg).…”

“…[6]) or 2-days-long sampling (e.g. [9]). Although the average distance between the sampling points is about 200 km, the differences between concentrations detected at the same time for different places are always within a factor of 2. respectively.…”
