Diablo Canyon Power Plant (DCPP) Units 1 and 2 Annual Radiological Environmental Operating Report, published April 30, 2014: Isotopic releases occurred in Japan and were carried by the jet stream to the west coast of the United States… [DCPP] periodically detected cesium (Cs-137) within market fish and cow meat due to deposition of Cs-137 from [Fukushima]… Fukushima Cs-137 was detected within one sample of monitoring well… Cs-137 was detected in three samples of market fish most likely due to rainwater washout of Fukushima Cs-137… Cs-137 was detected in [a] 2013 meat samples due to the Fukushima Japan nuclear accidents. This detection occurred… in October… [DCPP] detected cesium within milk, vegetation, and meat throughout 2011 [and] continued to detect cesium within groundwater, fish, vegetation, and meat throughout 2012.
Diablo Canyon Power Plant Units 1 and 2 Annual Radiological Environmental Operating Report, Apr. 30, 2013: Throughout 2012 [we] continued to detect cesium (Cs-137) within milk, vegetation, monitoring wells, fish, and meat due to deposition of Cs-137 from that event… Concentrations of cesium (Cs-137) were also detected in two shallow monitoring wells… This cesium was evaluated and attributed to rain-washout of Fukushima fallout… Due to topography and site characteristics, this groundwater gradient flow discharged into the Pacific Ocean… Cs-137 was detected in three samples of fish most likely due to rainwater washout of Fukushima Cs-137… Cs-137 was detected in 2012 vegetation samples… due to rainwater washout of Fukushima Cs-137 [that] was absorbed by plant life and the soil. DCPP… has routinely detected Cs-137 in plant life since March of 2011 due to this Fukushima event… Cs-137 was detected in… [cow] meat samples due to the Fukushima Japan nuclear accidents… Vegetation uptake and subsequent digestion by the animals were the source of these Cs-137 isotopes into the meat.
