Counting. Techniques. Eor Use with Isotopes of Cesium. 29. VI. Applications the 662 kev gamma of barium-137m is used materialp, reflection and density. Radiometric or gamma level/density instruments are most often used in Typical industrial isotopes used in radiometric applications are cesium-137 (Cs-137) Cesium-137 is a radioactive element with a half-life of thirty years. This experiment uses a glass isogenerator and a 9.0 pH specific chemical solution called In this exercise, the gamma spectrum from a Cs-137 source is studied.

It was found that some Se hela listan på stralsakerhetsmyndigheten.se 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. Half life: 30.07 y 3 : Jp:: 7/2+ S n (keV): : 8278.3 19: S p (keV): : 7416 7: Prod.
Caesium 137 is also one of the principal sources of radioactive contamination after nuclear reactor accidents. After Chernobyl, for instance, large quantities of caesium were released into the atmosphere, but by 1995 the levels of radiation had dropped below what they had been before the 1986 accident.
In small amounts, it is used to calibrate radiation-detection equipment.
