In many cases parents have been able to further reduce the cesium levels in their children by making changes to how food is selected.
In fact, most of the cesium present in today's oceans, Buesseler noted, is a remnant of atmospheric nuclear weapons testing conducted by the United States, France, and Great Britain during the 1950s and'60s.

Their first task was to obtain feed from low contamination areas, but even by doing this, they were unable to get the cesium level lower than 100 becquerels per liter.
Dividing up the contaminated soil by particle size and chemically processing the particles to remove the cesium could reduce the amount of soil that needs to go to the final storage destination.
The cesium did not constitute a public health concern, but it showed how radioactive material can be transported far from accidents sites, where it attaches to and is stored by sand grains.
When the decay of the physical half-life(2 years and 30 years) for each of the cesium isotopes is considered, the cumulative dose for the entire calendar year 2012 living continuously and exclusively at Suenomori Ranch would be estimated at 17 mSv Note 6.
Since one of the cesium isotopes(137Cs) has a half-life of 30 years, it constitutes the highest risk to the local population in the medium and long term, as it can be estimated that in the absence of decontamination it will remain in the environment for around three centuries.
Assuming the cesium concentration in the contaminated water at the nuclear power plant is 1,200 becquerels per liter, approximately 10 kilograms of bamboo charcoal could adsorb the cesium in 360,000 liters of contaminated water roughly equivalent to the amount of water in a 25-meter swimming pool.
In September, scientists from the government's Meteorological Research Institute and the Central Research Institute of the Electric Power Industry announced their findings at a meeting of the Geochemical Society of Japan, adding that some of the cesium will also flow into the Indian Ocean and, eventually, reach the Atlantic.
Fisher and Madigan ruled out the possibility that the cesium they measured had been carried on ocean currents or through the atmosphere by also sampling yellowfin tuna, which reside off California but do not migrate across the Pacific Ocean.
The cesium's close.
The Cesium Atomic Clock.
No sign of the cesium.
Therefore the cesium problem is also temporary.”.
The Cesium atomic clocks are very accurate and long lasting.
Figure the cesium and strontium have half-lives of about 30 years.
