High levels of strontium at Fukushima

More bad news for Japan and its stricken fishing industry: Tokyo Electric Power Company says radioactive strontium up to 240 times the legal concentration limit has been detected in seawater samples near an intake at the crippled Fukushima Daiichi nuclear plant.

According to Japan Times, the utility said the substance was also found in groundwater near the plant's Nos. 1 and 2 reactors. And Japan's Nuclear and Industrial Safety Agency said it is the first time that the substance has been found in groundwater—and that is necessary to carefully monitor the possible effects of the strontium on fishery products near the plant. Strontium tends to accumulate in bones and is believed to cause bone cancer and leukemia.

Strontium 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. Strontium-90, an isotope of strontium, 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.

And how much radiation has *really* drifted over here? I mean, TEPCO and the Japanese gov't at the very least have been misinforming (lying) since day one...

Sick of all the cover ups. Its time they tell the truth

Radioactive strontium is dangerous because it is in the same period as Calcium. That means that Strontium reacts similarly to Calcium. Strontium 90 has a half life of 28.8 years. Since Calcium is a major component of bones, Strontium 90 can bio-accumulate there, where the blood cells are made, and cause bone cancer or leukemia.

sweet zombie jesus! could you be a little bit more vague or inaccurate?

It is you 'dog' being vague and inaccurate.

See the passage below, straight from the EPA web site at http://www.epa.gov/rpdweb00/radionuclides/strontium.html

"Strontium-90 emits a beta particle with, no gamma radiation, as it decays to yttrium-90 (also a beta-emitter). Strontium-90 has a half-life of 29.1 years. It behaves chemically much like calcium, and therefore tends to concentrate in the bones and teeth."
