This basic release of specific technical information on this property of xenon-135
will be of scientific interest in the studies of nuclear structure and will aid in fundamental studies of reactor control.
However, radioactive elements, such as Krypton-85 or Xenon-135
, were not detected in the atmosphere after previous tests.
The two are xenon-133 and xenon-135
, and as their radioactivity is reduced to about half in about five days and nine hours, respectively, their existence suggests that a nuclear fission took place recently, according to Matsumoto.
amounts of xenon-133 and xenon-135
were found in gas samples from the No.
monitoring nuclear tests are xenon-135 (half-life, 9.
nuclear test, the ratio of xenon-135 to xenon-133 may indicate whether
event; xenon-135 was presumably not detected because of its shorter
2 reactor xenon-133 and xenon-135
, which are typically generated by nuclear fission and have relatively short half-lives, it touched on the possibility that melted fuel inside the reactor may have temporarily gone critical.
detected small amounts of xenon-133 and xenon-135
in gas samles from the No.
Air Force selected ARSA in part because it is the only system that can detect xenon-135
to meet the CTBT obligations.
The plant operator said it has judged that spontaneous fission, which it says occurs at a constant rate, has generated xenon-133 and xenon-135
at its crisis-hit No.
It detected radioactive xenon-133 and xenon-135
, products of uranium or plutonium fission, in gases collected Tuesday from the reactor.
