Jiji Press, Oct. 14, 2014: Cesium Level Rises in TEPCO Plant Well — [TEPCO] on Tuesday reported a sharp rise in cesium levels in water collected from an observation well near the sea [on] Monday [with] a record 251,000 becquerels of radioactive cesium per liter, 3.7 times the cesium level… [last] Thursday… Monday’s reading was the highest level… from any of these wells… The samples in question also contained 7.8 million becquerels of beta particle-emitting radioactive substances, such as strontium-90, per liter, also a 3.7-fold increase.
ITAR-TASS (Russian News Agency), Oct. 14, 2014 (emphasis added): Highest radiation in ground water at Japan’s NPP after nuclear disaster… The highest radiation level was registered in subsoil water taken from a technical well at 1st and 2nd power units at Fukushima-1.., [TEPCO] said on Tuesday. The underground water sample was taken on October 13… Company’s experts said that a surge in radiation was linked with the impact of a typhoon raging in the locality, when heavy rain triggered spread of radiation-contaminated particles in underground water. Now nuclear plant’s specialists are pumping out ground water urgently to prevent it from leaking into the ocean.
Kyodo News, Oct 14, 2014 (Google translation): … record high values of cesium, the influence of the typhoon in Fukushima first nuclear power plant… from the water of the well in the seawall of the Fukushima Daiichi nuclear power plant Units 1 and 2 [cesium is 251,000] becquerels per liter… manganese 54 is… 700… cobalt 60 [is 3,600]… [TEPCO] found under the influence of typhoon No. 18 earlier this month, contaminated water that has accumulated in the piping has been spreading. Both record high values in groundwater…
Note that the most recent stontium-90 test results for well No. 1-6 published by Tepco on Oct. 1 show that levels of Sr-90 are virtually equal to Gross Beta. This means the Oct. 13 Sr-90 levels are near 7,800,000 Bq/L — 26,000,000 times the EPA limit for Sr-90 in water (0.3 Bq/L).
