Mainichi, Dec. 3, 2013: [Tepco] said on Dec. 2 that it has detected radioactive materials that topped 36,000 times the permissible level in underground water […] strontium-90 and other radioactive substances that emit beta rays were detected at a level of 1.1 million becquerels per liter (1.1 billion Bq/m³) […] east of the No. 2 reactor, about 40 meters from the ocean. […] It has been feared that highly contaminated water is leaking to the ground from a trench that stretches from the No. 2 reactor building to the sea bank. The radioactive isotope detected this time suggests the possibility of radioactive materials remaining outside the trench. […]
Arirang News, Dec. 3, 2013: The Japanese media on Tuesday reported an all-time high radiation level in an observation well at the crippled Fukushima Daiichi nuclear power plant. […] 1.1 million becquerels of beta ray-emitting radioactive material had been detected per liter […] more than the previous record-high of 910-thousand becquerels per liter detected on November 25th.
Jiji Press, Nov. 28, 2013: TEPCO Puts Off Tainted Groundwater Removal at Fukushima Plant […] a shortage of water storage tanks has forced it to postpone removal of contaminated groundwater at its crippled Fukushima No. 1 nuclear power station. The postponement would allow radioactive groundwater to continue to flow beyond soil hardened with chemicals between the No. 2 and No. 3 reactors and into the sea.
