摘要

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