Tests showed the waste, which likely contains strontium and cesium, wasn't spreading into the river or groundwater.
Cesium remains the most widely dispersed isotope while concerns remain over long-term contamination from strontium and plutonium.
The origin of the goods is determined by measuring the levels of strontium isotopes in the material.

From a public health perspective, the most important isotopes are short-lived isotopes of iodine (like Iodine-131), Cesium-137, Strontium-90, and possibly Plutonium-239.
It uses two ion exchange processes to remove the radioactive elements Cesium-134 (Cs-134), Cesium-137 (Cs-137) and Strontium-90 (Sr-90) from the seawater.

Different geographic regions have different levels of strontium, so by examining those isotopes, archaeologists are able to figure out where materials originated.

The first is a bulk removal, ion exchange process in which sodium is swapped for cesium or strontium within an inorganic, crystalline structure.

Some end up in the milk supply (Strontium-90) and will behave as calcium, collecting in your bones and contributing to bone cancer and leukemia.
Some argue that other preparations, such as daily strontium ranelate, which increases the formation of healthy new bone while simultaneously decreasing bone destruction, are more convenient to take.
They have now produced a laboratory report from France that records chronic intoxication showing abnormally high levels of the metal chromium and eight times the normal level of strontium.
Strontium 90 for instance acts very much like calcium.

The danger from nuclear waste comes mainly from dust-like particles containing radioactive isotopes of iodine, cesium and strontium that could be released if the reactor fuel is allowed to become too hot.
The company will further investigate the possible spread of contamination and its potential impact in the ocean, including the existence of beta radiation that could contain harmful strontium, company spokesman Yoshikazu Nagai said.
IAEA-led team was fanning out in western Georgia in search of the remaining two of a batch of eight abandoned devices containing strontium-90, another radioactive element, which had been used in generators for communication stations.
Cancer incidence in children under age ten living near New York and New Jersey nuclear plants increased 4-5 years after increases in average Strontium-90 in baby teeth, and declined 4-5 years after Sr-90 averages dropped.
