Abstract:
A total of 118 samples were analyzed using HPGe γ-spectrometry. (131)I, (134)Cs, (137)Cs and (136)Cs were detected in aerosol air samples that were collected 22 days after the accident with values of 1720 µBq m(-)³, 247 µBq m(-)³, 289 µBq m(-)³ and 23 µBq m(-)³, respectively. (131)I was detected in rainwater and soil samples and was also measurable in vegetables collected between April 2 and 13, 2011, with values ranging from 0.55 Bq kg(-1) to 2.68 Bq kg(-1). No (131)I was detected in milk, drinking water, seawater or marine biota samples.
