Fukushima: "As of 2014, a peer reviewed estimate of the total was 340–800 PBq, with 80% falling into the Pacific Ocean.[8] Radiation continues to be released into the Pacific via groundwater." Chernobyl: "5.2 EBq (5,200 PBq)" From: https://en.wikipedia.org/wiki/Comparison_of_Fukushima_and_Chernobyl_nuclear_accidents https://en.wikipedia.org/wiki/Comparison_of_Fukushima_and_Ch...
