Barium 137 half life

Naturally occurring barium (Ba) is a mix of six stable isotopes and one very long-lived. The only notable exceptions are 133Ba, which has a half-life of 10. Ba (1 days), and 137mBa (minutes), which is the decay product .

Caesium-1(155Cs , Cs-137), cesium-13 or radiocaesium, is a radioactive isotope of. Ba-137m has a half-life of about 1seconds, and is responsible for all of the emissions of gamma rays in samples of caesium-137. Each generator contains µCi of Cs-137. The generator can produce up to 10small aliquots of the short-lived Ba-137m isotope with a half-life of 2.

Radioactive Half-life of Barium-137m by Dr. One of the characteristics often used to describe radioisotopes is half-life. In this experiment, the half-life of Ba-137m will be determined.

Hands-on Investigations: Measuring the Half Live of a Radioactive Sample. A FEW years ago, Wasserman, Twardock and Comarinvestigated the metabolic dissociation of caesium-137–barium-137m in animals. Equipment Spectech isotope generator kit, Geiger tube with power supply and counter, sample tray, meter stick, trays, stop watch.

Cesium-1is a radioactive element with a half-life of thirty years. Its decay in the formation of Ba-1with a very short half-life. Now that you have your data, it’s time to calculate the half-life of barium-137m!
