A metallic chemical element (symbol Cs) with an atomic number of 55. released in the event of a nuclear accident in conjunction with their half-lives and transfer from The radioactivity certificate must indicate the caesium-134 and -137 and 

Thus, this isotope is confined in a lead container to prevent it from being dispersed to the environment. If Cesium-137 is released, it would take 30 years before half of it decays or disappears. 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). The metastable isotope (barium-137m) is rapidly converted to stable barium-137 (half-life of about 2 2011-09-05 Cesium-137 has a long half-life of 30.19 years based on a human life span, while the activity of iodine-131, for example, is halved within 8 days due to radioactive decay. From a radiobiological point of view, besides Cs-137, cesium-134 is also of less importance. Caesium 137 is a radioactive element with a relatively long half-life of 30.15 years.

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). The metastable isotope (barium-137m) is rapidly converted to stable barium-137 (half-life of about 2 The half-lives of Cs-134 and Cs-137 are approximately 2 years and 30 years, respectively. Because of the continual emission of radiation, people could be exposed to radiation from Cs-137 or Cs-134 released to the environment.

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). The metastable isotope (barium-137m) is rapidly converted to stable barium-137 (half-life of about 2 The half-lives of Cs-134 and Cs-137 are approximately 2 years and 30 years, respectively.

The biological half life of 137Cs in children was determined to be 53 ± 12 days by means of urinary assay and whole-body counting of the control group. This half life value and the average urine 137Cs levels at the six institutions were then used to estimate the average 137Cs body burdens at these institutions.
