caesium

He said detection of the radioactive element caesium outside the No. 1 reactor today was "a bad sign" for a core meltdown.

Caesium reduces the size of your picture up to 90%, preserving the original quality.

Previous releases of radioactive iodine and caesium had shown that material from the core of at least one reactor has been released.

Officials told the BBC that they had detected what may be the missing Caesium-137, adding that it may have been melted down.

Meanwhile, these methods have been modified and improved by newly developed caesium magnetometers and by proton-procession magnetometers .

The Caesium-137 may be buried in a scrap yard under tonnes of metal, and local officials believe it could have been melted down.

These included caesium-137 and iodine-131, Nisa said, noting that levels began to decrease after some time.

They touched the powder and daubed it on their bodies like carnival glitter, taking fragments of the radioactive caesium chloride salt home.

The main radionuclides representing health risk are radioactive caesium and radioactive iodine.

His discoveries, which won him the Nobel prize, led to the caesium atomic clock and the hydrogen maser.

Reports say that radioactive caesium is similar to kalium, a commonly used fertiliser and will be easily absorbed by sunflowers.

The recall was started after tests found up to 30. 8 becquerels of caesium per kilo of Meiji Step powdered milk.

Tokyo's tap water, where iodine turned up Friday, now has caesium as well.

Radioactive caesium-137 also appeared in one of the samples, but at levels below the legal limit.

Iodine-131 and caesium are more damaging, however. Iodine is actively taken up by the thyroid gland to make hormones.

Japanese milk powder maker Meiji has recalled its baby formula after discovering radioactive caesium in the product.

What is more, caesium particles tend to lurk in the grass, which means radiation is more of a risk at toddler height than for adults.

Caesium-137 is of particular concern as it can stay in the environment and potentially cause havoc for hundreds of years.

Caesium- 134 is produced in nuclear reactors, not directly by fission, but by the reaction.

who pioneered in spectrum analysis and codiscovered the elements caesium and rubidium. He introduced the Bunsen burner in 1855.

Radioactive caesium has also been detected.

Vast amounts of caesium-137 were distributed across 40 per cent of Europe's surface after Chernobyl.

Caesium 137 is the preferred source type.

Low dose exposure to caesium-137, even over a long period of time, is perhaps not as damaging to health as we would have predicted.
