Radioactive Analysis for Underground Water at Fukushima Daiichi, Oct 9, 2014:

Radiological Fact Sheet; [It's] possible to dissolve Co-60… making it a potential inhalation or ingestion hazard… Inhaled Co-60 contamination can give high radiation dose to lungs… Ingested insoluble Co-60 can give high radiation dose to the intestinal tract, while soluble Co-60 distributes fairly evenly through the body… “hot” particles can give very high dose locally, in area of particle… 45% of Co-60 that enters the blood is evenly distributed through the body…http://www.tepco.co.jp/en/nu/fukushima-np/f1/smp/2014/images/2tb-east_14100902-e.pdf
Michael Maqua, nuclear expert and head of plant engineering at GRS, Oct. 10, 2014: Over the past days, the concentration of radioactive substances in the groundwater has increased significantly at some of the plant’s measuring points and, according to TEPCO, this was caused by the recent heavy rains… Contaminated water… is in fact constantly reaching sea water… caused, for example, by leakages in building structures http://www.dw.de/is-fukushima-capable-of-withstanding-a-super-typhoon/a-17987229
