Radioactive strontium one million times over limit into ocean from Fukushima
“The source of the beta radiation in the water is likely to include strontium 90, which if absorbed in the body through eating tainted seaweed or fish, accumulates in bone and can cause cancer,”
Fukushima floods into Pacific Ocean, Strontium becomes One Million Times over Limit, The Canadian, 07 DECEMBER 2011 The woes of Fukushima are far from over as the plant’s owner, the Tokyo Electric Power Company (TEPCO), announced recently that a purification mechanism has leaked at least 45 tons of highly radioactive water, some of which ended up flowing directly into the ocean. TEPCO officials are reportedly in the process of investigating the situation to determine the extent of the damage caused.
A BusinessWeek report explains that the water also contained 1.8 millisieverts per hour of gamma radiation and 110 millisieverts of beta radiation, both of which are damaging forms of ionizing radiation emitted from nuclear waste that can cause cell damage, leukemia, cancer and various other severe health problems.”The source of the beta radiation in the water is likely to include strontium 90, which if absorbed in the body through eating tainted seaweed or fish, accumulates in bone and can cause cancer,” said Tetsuo Ito, head of Kinki University’s Atomic Energy Research Institute, concerning the situation. Data gathered found that strontium levels in the water are has high as one million times the government’s maximum safety threshold.
Strontium ( /ˈstrɒntiəm/) is a chemical element with the symbol Sr and the atomic number 38. An alkaline earth metal, strontium is a soft silver-white or yellowish metallic element that is highly reactive chemically. The metal turns yellow when exposed to air. It occurs naturally in the minerals celestine and strontianite. While natural strontium is stable, the synthetic 90Sr isotope is present in radioactive fallout and has a half-life of 28.90 years. Both strontium and strontianite are named after Strontian, a village in Scotland near which the mineral was first discovered.
