“…The average 137 Cs concentration value (65 Bq kg À1 ) is higher than when compared with those from other parts of Turkey ( € Ozmen et al, 2014;€ Oztürk et al, 2013;Kucukomeroglu et al, 2012). On the other hand, the average concentration value obtained from this study is lower than the values reported for some other provinces of Turkey (Kurnaz et al, 2007;Celik et al, 2008). It may be useful to remember that the recommended screening limits (RSL) in the soil (NCRP, 1999) for a scenario that includes open fields and forested sites are: 150 Bq kg À1 for 137 Cs.…”

“…Due to their high concentration of radionuclides, studies report that Brazil nuts are radioactive (Turner et al 1958;Smith 1971). The occurrence of cancer is among the risks associated with the ingestion of radioactive foods, and monitoring is a form of health protection (Irigaray et al 2007;Celik 2008).…”

A study was carried out to evaluate the association of levels of radioactivity, selenium and aflatoxin in shelled Brazil nuts, which were classified in different sizes, for export. The selenium determinations were performed by inductively coupled plasma optical emission spectrometry (LOQ = 3.0 µg g -1 ), and aflatoxins were detected by Liquid chromatography-mass spectrometry (LOQ = 0.85 µg kg -1 ), recovery rates were between 92 and 100%. Radioactivity was measured by high-resolution gamma spectrometry. The selenium mean concentration was (22.7 ± 7.4) µg g Ra. There was no statistically significant association between the level of selenium and the activity of radionuclides, however, there was correlation between the radionuclides. Aflatoxins above the quantification limit were not found. Keywords: radioactivity; selenium; Bertholletia excelsa. Castanha do Brasil: determinação de elementos naturais e aflatoxinas resUMoUm estudo foi realizado para avaliar a associação dos níveis de radioatividade, selênio e aflatoxinas em castanha-do-Brasil descascada, que foram classificadas em diferentes tamanhos, para exportação. As determinações de selênio foram realizadas por espectrometria de emissão óptica com plasma indutivamente acoplado (LOQ=3,0 µg kg -1 ) e aflatoxinas foram detectadas por LC-MSMS (LOQ=0,85 µg kg -1 ), as taxas de recuperação ficaram entre 92 e 100%. A radioatividade foi medida por espectrometria gama de alta resolução. A concentração média de selênio foi de (22,7 ± 7,4) Ra. Não houve associação estatisticamente significativa entre o nível de selênio e a atividade de radionuclídeos, no entanto, houve correlação entre os radionuclídeos. Não foi encontrado aflatoxinas acima do limite de quantifcação. PAlAvrAs-chAve: radioatividade, selênio, bertholletia excelsa.

“…In the tea field soils in the eastern part of the Black Sea Mountains, 137 Cs activity in surface soil (top 0.5 cm of the soil) was 4000-4500 Bq kg -1 in 1988 (Celik et al 2008). Twenty months after the Chernobyl accident, approximately 80% of the radiocesium was still present at a depth of 10 cm in the tea plantation soil (Yeşın and Çakir 1989).…”

We investigated radiocesium distribution in tea plants (Camellia sinensis L. var. sinensis) of Saitama Prefecture, located approximately 200-250 km away from Tokyo Electric Power Company's Fukushima Daiichi nuclear power plant. In 2012, more than 2500 samples of tea plants were analyzed. We found differences in radiocesium concentration among tea plant cultivars, which appeared to be attributable mainly to the leaf morphology and depth of the leaf layer in tea plants. Furthermore, the radiocesium concentration in the first tea crop showed a strong correlation with that in spring skiffing.
