Data on atmospheric ¹²⁹I concentrations and ¹²⁹I/¹³⁷Cs ratios for suspended air particulate matter dispersed in eastern Japan just after the 2011 nuclear accident in Fukushima, Japan.

ABSTRACT: Data of the atmospheric activity concentrations (in Bq/m³) of ¹²⁹I dispersed into the environment as aerosol immediately after the nuclear accident at Fukushima Daiichi Nuclear Power Plant in 2011 are presented. The radioactivity of ¹²⁹I was determined in suspended particulate matter (SPM) collected on filter tapes at 41 SPM monitoring sites in Fukushima and other prefectures in eastern Japan including the metropolitan area. For quantitative determination of ¹²⁹I in SPM samples by accelerator mass spectrometry (AMS), ¹²⁹I was chemically separated. Prior to the ¹²⁹I measurement, the ¹³⁷Cs activity was determined for the same SPM sample by gamma-ray spectrometry using Ge-semiconductor detectors. Combining activity c
