Dynamics of atmospheric ¹³¹I in radioactive plumes in eastern Japan immediately after the Fukushima accident by analysing published data.

ABSTRACT: The spatio-temporal distribution of atmospheric radioiodine immediately after the Fukushima Daiichi Nuclear Power Plant (FD1NPP) accident has not yet been clarified due to very limited observed data, compared with atmospheric radiocaesium data. Here, we first revealed that the ratios of ¹³¹I (decay-corrected to March 11, 2011) to ¹³⁷Cs in radioactive plumes were divided into three groups (A, B, and C) by analysing all published data on atmospheric ¹³¹I concentrations independently measured immediately after the accident in eastern Japan. Groups A and C were found regardless of whether the measurement sites were located in eastern Fukushima or Kantou areas, while group B was observed only in the eastern Kantou area. The ratios in group A were approximately e
