Cesium-131, a radioactive isotope of cesium, is used with iodine-125, another radioactive isotope, in a brachytherapy seed. According to the American Brachytherapy Society, a brachytherapy seed ...

The cesium decays into a short-lived radioactive isotope of barium, which further decays into a stable form of barium. “Bombs don’t have cesium; bombs have uranium,” he said. “When there’s fission, ...

Cesium-137 is a radioactive isotope that can pose a significant health risk in the event of a nuclear attack. Exposure to significant quantities of Cesium-137 can lead to severe skin burns, ...

For years, scientists questioned why levels of a radioactive isotope known as cesium-137 have remained surprisingly high in wild boars rooting around Germany and Austria, while decreasing in other ...

137Cs, or cesium-137, is a radioactive isotope of cesium produced during nuclear fission, which is the process of splitting an atom into two atoms of a different element.

And given that nuclear reactors and nuclear weapons leave slightly different contamination signatures — with distinct ratios of cesium-135 to cesium-137 isotopes — the researchers determined ...

The ratio of the two types of cesium is not always the same -- for example, fallout from the Chernobyl nuclear accident had an isotope fingerprint different from that of the nuclear weapons tests ...

The source was Cesium-137, ... With a 30-year half-life, cesium isotopes can present a long-lasting threat if not properly disposed of at a storage facility.

They tended to register for high levels of a certain radioactive isotope known as cesium-137 — an isotope associated with nuclear reactors, among other things. And in 1986, one particular nuclear ...

Cesium-137 is one of the most common fission products in nuclear waste, and cobalt-60 (also a byproduct of fission) is used in radiation therapies. When testing with the cesium isotope, ...

Scientists have known for years that a population of wild boars in southern Germany contained incredibly high levels of radioactive cesium. They long suspected that much of this is due to the 1986 ...
