AB  - Radionuclides from the reactor accident at the Fukushima Dai-ichi Nuclear Power 
      Plant were observed in the surface air at stations in Hanoi, Dalat, and Ho Chi 
      Minh City (HCMC) in Vietnam, about 4500 km southwest of Japan, during the period 
      from March 27 to April 22, 2011. The maximum activity concentrations in the air 
      measured at those three sites were 193, 33, and 37 muBq m(-3) for (131)I, 
      (13)(4)Cs, and (13)(7)Cs, respectively. Peaks of radionuclide concentrations in 
      the air corresponded to arrival of the air mass from Fukushima to Vietnam after 
      traveling for 8 d over the Pacific Ocean. Cesium-134 was detected with the 
      (134)Cs/(137)Cs activity ratio of about 0.85 in line with observations made 
      elsewhere. The (131)I/(137)Cs activity ratio was observed to decrease 
      exponentially with time as expected from radioactive decay. The ratio at Dalat, 
      where is 1500 m high, was higher than those at Hanoi and HCMC in low lands, 
      indicating the relative enrichment of the iodine in comparison to cesium at high 
      altitudes. The time-integrated surface air concentrations of the 
      Fukushima-derived radionuclides in the Southeast Asia showed exponential decrease 
      with distance from Fukushima.
