Fukushima Mystery? TV: Japan expert says radiation levels in ocean too high to be explained by groundwater flow alone — Must be coming from “other contamination routes” entering Pacific — “Devastating impact” to come? (VIDEO)

Yoichiro Tateiwa, NHK reporter: [Professor Jota] Kanda argues government statistics don’t add up. He says a daily leakage of 300 tons doesn’t explain the current levels of radiation in the water.
Jota Kanda, Tokyo University professor: According to my research there are now 3 gigabecquerels [3 billion becquerels] of cesium-137 flowing into the port at Fukushima Daiichi every day. But for the 300 tons of groundwater to contain this much cesium-137, one liter of groundwater has to contain 10,000 becquerels of the radioactive isotope.
NHK: Kanda’s research and monitoring by Tepco puts the amount of cesium-137 in the groundwater around the plant at several hundred becquerels per liter at most. He’s concluded that radioactive isotope is finding another way to get into the ocean. He’s calling on the government and Tepco to identify contamination routes other than groundwater.
Kanda: If we focus on groundwater too much without contemplating other causes, the situation won’t be resolved. There must be routes other than groundwater that are contaminating the ocean. So what we have to do now is consider all possibilities as we figure out a solution to the problem.
NHK: Professor Kanda says the volume of radioactive particles discharged into the ocean is much smaller than the volume released immediately after the accident. But, he says there may be other sources of contaminated water stored up inside the plant’s infrastructure. He says that water is highly contaminated, and if it gets into the ocean it will again have a devastating impact.
