Caesium-134 has a half-life of 2.0652 years. It is produced both directly (at a very small yield because 134 Xe is stable) as a fission product and via neutron capture from nonradioactive 133 Cs (neutron capture cross section 29 barns), which is a common fission product.
The radioactive 135 Cs has a very long half-life of about 2.3 million years, the longest of all radioactive isotopes of caesium. 137 Cs and 134 Cs have half-lives of 30 and two years, respectively. 137 Cs decomposes to a short-lived 137m Ba by beta decay, and then to nonradioactive barium, while 134 Cs transforms into 134 Ba directly. The ...

Caesium-134 is found in spent nuclear fuel but is not produced by nuclear weapon explosions, as it is only formed by neutron capture on stable Cs-133, which is only produced by beta decay of Xe-133 with a half-life of 3 days. Cs-134 has a half-life of 2 years and may be a major source of gamma radiation in the first 20 years after discharge.
After entering the body, caesium gets more or less uniformly distributed throughout the body, with the highest concentrations in soft tissue. [17]: 114 However, unlike group 2 radionuclides like radium and strontium-90, caesium does not bioaccumulate and is excreted relatively quickly. The biological half-life of caesium is about 70 days.
