Radiocaesium accumulation in rice cultivars in a low-potassium paddy field in Fukushima

The accumulation of radiocaesium in the grains of 15 rice cultivars was monitored in 2014 and 2015. The study area was a local paddy field with low soil potassium concentrations, where highly radiocaesium contaminated rice had been commercially harvested because of the Fukushima Daiichi Nuclear Powe...
