Hidden Fukushima nuclear waste being released into ocean — ‘Surprisingly’ high levels of radiation now detected along Pacific coast and in groundwater far from reactors — Expert: No one expected this — “Alarming example of how radiation has spread”

Newsweek, Oct 4, 2017 (emphasis added): Radiation From Fukushima Nuclear Disaster Discovered in Sand and Groundwater 60 Miles Away… the beach groundwater is even 10 times more radioactive than the ocean directly next to the Fukushima plant.
Gizmodo, Oct 4, 2017: Fukushima’s Radioactive Waste Is Leaking From an Unexpected Source — A new and unexpected source of radioactive material left over from the 2011 Fukushima nuclear disaster has been found up to 60 miles away along coastlines… The discovery shows that damaged nuclear reactors are capable of spreading radiation far from the meltdown site, and in some surprising ways.
UPI, Oct 3, 2017: Beaches found releasing radioactive cesium into ocean 60 miles from Fukushima… Scientists have discovered a surprising new source of radioactive cesium… [Researchers] found unusually high levels of radioactive cesium-137 in the groundwater beneath several beaches… “No one expected that the highest levels of cesium in ocean water today would be found not in the harbor of the Fukushima Dai-ichi nuclear power plant, but in the groundwater many miles away below the beach sands,” WHO researcher Virginie Sanial said…
Fox News, Oct 3, 2017: Fukushima’s radioactive cesium found an unexpected hiding spot… The find wasn’t just a surprise, but significant. As the researchers write, “Aside from the aquifer beneath [the plant], the highest recorded present-day activities of [cesium-137] in the aqueous environment in Japan are associated with brackish groundwater underneath beaches.”
IFL Science, Oct 2, 2017: Scientists investigating the Fukushima Daiichi nuclear power plant in Japan have found an unexpected source of radioactive material… [It’s] an alarming example of how radiation from the reactor has spread… “It is as if the sands acted as a ‘sponge’ that was contaminated in 2011 and is only slowly being depleted,” said study co-author Ken Buesseler…
Study – Unexpected source of Fukushima-derived radiocesium to the coastal ocean of Japan, Sep 26, 2017: [T]he highest radiocesium (137Cs) activities outside of the power plant site were observed in brackish groundwater underneath sand beaches… During our study period, we found the highest cesium-137 (137Cs) levels (up to 23,000 Bq⋅m−3) outside of the FDNPP site not in the ocean, rivers, or potable groundwater, but in groundwater beneath sand beaches over tens of kilometers away from the FDNPP. Here, we present evidence of a previously unknown, ongoing source of Fukushima-derived 137Cs to the coastal ocean… This estimated ocean 137Cs source (0.6 TBq⋅y−1) is of similar magnitude as the ongoing releases of 137Cs from the FDNPP site for 2013–2016, as well as the input of Fukushima-derived dissolved 137Cs via rivers… This unexpected and ongoing 137Cs source requires further investigation…
