dc.description.abstract | The opportunity to measure the concentrations of ³H and ³⁶Cl released by the Fukushima nuclear accident in 2011 directly in rain was lost in the early stage of the accident. We have, however, been able to reconstruct the deposition record of atmospheric ³H and ³⁶Cl following the accident using a bore hole that was drilled in 2014 at Koriyama at a distance of 60 km from the accident. The contributions of ³H and ³⁶Cl from the accident are 1.4 × 10¹³ and 2.0 × 10¹² atoms m⁻² respectively at this site. Very high concentrations of both ³H (46 Bq L⁻¹) and ³⁶Cl (3.36 × 10¹¹ atoms L⁻¹) were found in the unsaturated soil at depths between 300 and 350 cm. From these, conservative estimates for the ³H and ³⁶Cl concentrations in the precipitation in the ~ 6 weeks following the accident were 607 Bq L⁻¹ and 4.74 × 10¹⁰ atoms L⁻¹, respectively. A second hole drilled in 2016 showed that ³H concentrations in the unsaturated soil and shallow groundwater had returned to close to natural levels, although the ³⁶Cl concentrations were still significantly elevated above natural levels. | en |
