Can cesium-137 explode?
Cesium-137 is an especially dangerous fission product because of its high yield during fission, moderate half-life, high-energy decay pathway, and chemical reactivity. Because of these properties, cesium-137 is a major contributor to the total radiation released during nuclear accidents.
What happens if you eat cesium-137?
HIGHLIGHTS: Exposure to stable or radioactive cesium occurs from ingesting contaminated food or drinking water or breathing contaminated air. High levels of radioactive cesium in or near your body can cause nausea, vomiting, diarrhea, bleeding, coma, and even death.
Can you touch cesium?
Because of this high reactivity, caesium metal is classified as a hazardous material. It is stored and shipped in dry, saturated hydrocarbons such as mineral oil. It can be handled only under inert gas, such as argon.
What element is atomic number 37?
rubidium
So there we have rubidium, the explosive red element number 37 in the periodic table.
Does cesium glow blue?
A dangerous glow Because the exposed caesium chloride gave off an eerie blue glow, it became a popular talking point. Samples of the glowing powder were shared around.
Is cesium-137 naturally occurring?
Despite its prevalence in spent nuclear fuel and nuclear waste, cesium-137 is actually extremely rare. Its half-life is too short for it to persist from natural fission sources, and on earth it is a synthetic isotope only.
Is cesium-137 rare?
Can cesium be used in a bomb?
Cesium-137 is an isotope used medical equipment such as blood irradiators. However, it is also the most dangerous of all radioactive isotopes. If used in a dirty bomb, the highly dispersible powder would contaminate an area for years, costing billions of dollars in evacuation, demolition and clean-up.
What is the chemical symbol of Cesium 137?
Radionuclide Basics: Cesium-137 Cesium (chemical symbol Cs) is a soft, flexible, silvery-white metal that becomes liquid near room temperature, but easily bonds with chlorides to create a crystalline powder. The most common radioactive form of cesium is Cs-137.
What is the fission yield of Cesium 137 in nuclear reactions?
The fission yield of cesium-137 in nuclear reactions is relatively high, about 6 atoms of cesium-137 are produced per 100 fission events. Cesium-137 has a radioactive half-life of about 30 years and decays by beta decay either to stable barium-137 or a meta-stable form of barium ( barium -137m).
What is the most common radioactive form of cesium?
The most common radioactive form of cesium is Cs-137. Cesium-137 is produced by nuclear fission The splitting of an atomic nucleus into at least two other nuclei with the release of a relatively large amount of energy. Fissioning that occurs without any outside cause is called “spontaneous fission.”
How is cesium-137 produced?
Cesium-137 is produced by nuclear fission fission The splitting of an atomic nucleus into at least two other nuclei with the release of a relatively large amount of energy. Fissioning that occurs without any outside cause is called “spontaneous fission.” for use in medical devices and gauges.
