摘要

We present measurement results of airborne fission products in Chapel Hill, NC, USA, from 62 d following the March 11, 2011, accident at the Fukushima Dai-ichi nuclear power plant. Airborne particle samples were collected daily in air filters and radio-assayed with two high-purity germanium (HPGe) detectors. The fission products ~(131)I and ~(137)Cs were measured with maximum activity concentrations of 4.2 ± 0.6 mBq/m~3 and 0.42 ± 0.07 mBq/m~3 respectively. Additional activity from ~(131,132)I, ~(134,136,137)Cs and ~(132)Te were measured in the same air filters using a low-background HPGe detector at the Kimballton Underground Research Facility (KURF).
