Evidence of 131 I and 134,137 Cs activities in Bordeaux, France due to the Fukushima nuclear accident

Global deposition and transport efficiencies of radioactive species with respect to modelling credibility after Fukushima (Japan, 2011)

“…Fig. 5 depicts the comparison of deposition over Europe using measurements from several research groups (Baeza et al, 2012;Barsanti et al, 2012;Carvalho et al, 2012;Evrard et al, 2012;Ioannidou et al, 2012;Kritidis et al, 2012;Lepp€ anen et al, 2013;Lujaniene et al, 2012;Perrot et al, 2012;Pham et al, 2012;Potiriadis et al, 2013;Povinec et al, 2012). Based upon these few measurements, we conclude that the model shows a good agreement with observations of deposition of 137 Cs.…”

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

“…[4,6,9]; these data are shown in Table 8.1. The results of the current work were also compared to measurements performed following the Chernobyl nuclear accident [3].…”

“…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. HPGe detectors possess excellent energy resolution which facilitates the detection of weak sources of radiation that would otherwise be lost in the background if detectors with poorer energy resolution, such as inorganic scintillators were used [11].…”

Facteurs de transfert du césium au lait et à la viande déterminés à partir de mesures faites en France en 2011 à la suite de l’accident de Fukushima-Daichi

“…L'activité en 134 Cs dans la végétation de prairie prélevée dans la région d'Agen (0,06 ± 0,03 à 0,41 ± 0,15 Bq.kg -1 ) est comparable aux résultats des mesures provenant de la région de Bordeaux (0,22 à 0,53 Bq.kg -1 ) (Perrot et al, 2012) For each point denoted < LD, the value shown in the figure is the value of the detection limit.…”
