It was a single isotope which has a half-life of about 30 years. To show how the activity vs. time graph for a single isotope differs from the dose rate due to Chernobyl (in the open air), the adjacent chart is shown with calculated data for a hypothetical release of 106 Ru.
The German environmental minister was given the authority over reactor safety as well, a responsibility the minister still holds today. The Chernobyl disaster is also credited with strengthening the anti-nuclear movement in Germany, which culminated in the decision to end the use of nuclear power made by the 1998–2005 Schröder government.

Estimated number of deaths from the Chernobyl nuclear disaster A map showing caesium-137 contamination in the Chornobyl area in 1996. The Chernobyl disaster of 26 April 1986 triggered the release of radioactive contamination into the atmosphere in the form of both particulate and gaseous radioisotopes.

Caesium-137, along with other radioactive isotopes caesium-134, iodine-131, xenon-133, and strontium-90, were released into the environment during nearly all nuclear weapon tests and some nuclear accidents, most notably the Chernobyl disaster and the Fukushima Daiichi disaster. Caesium-137 in the environment is substantially anthropogenic ...
It also plays a major role as a radioactive isotope present in nuclear fission products, and was a significant contributor to the health hazards from open-air atomic bomb testing in the 1950s, and from the Chernobyl disaster, as well as being a large fraction of the contamination hazard in the first weeks in the Fukushima nuclear crisis.
It constitutes most of the radioactivity still left from the Chernobyl accident and is a major health concern for decontaminating land near the Fukushima nuclear power plant. [16] 137 Cs beta decays to barium-137m (a short-lived nuclear isomer) then to nonradioactive barium-137. Caesium-137 does not emit gamma radiation directly, all observed ...
The main isotope responsible is 135 Xe, mainly produced by natural decay of 135 I. 135 I is a weak neutron absorber , while 135 Xe is the strongest known neutron absorber. When 135 Xe builds up in the fuel rods of a reactor, it significantly lowers their reactivity , by absorbing a significant amount of the neutrons that provide the nuclear ...
