Ray Decay Data Standards for Detector Calibration and Other Applications was established by the IAEA in the late 1990s to discuss the quality of the relevant data and define a suitable programme to resolve various issues. The participants in the CRP were specialists in γ ray spectroscopy and in the related areas of decay data

Later experiments used the isotope dilution technique with a mass spectrometer to determine the number of Cs137 atoms in a given sample, and 47~ absolute P-

The notes on beta spectra that accompany the table are excellent. If N(p)is the probability that an electron is emitted with momentum betweenp and p+dp, then, if the neutrino is massless we have: N(p)=CF(Z,p)p2(E 0 − E e)2 where C is a collection of constants. 1960-06-01 The resulting decay scheme with levels at 79. 158, 381 and '137 keV is in excellent agreement with previous work. Spin and parity assignments are made for these levels.

137 Cs decay scheme showing half-lives, daughter nuclides, and types and proportion of radiation emitted. 137 Cs gamma spectrum. The characteristic 662 keV peak does not originate directly from 137 Cs, but from the decay of 137m Ba to its stable state. Caesium-137 has a half-life of about 30.17 years.

The great majority of the Cs-137 nuclei Cs-137 is a long-lived parent nuclide which has a half-life of 30.07 years and decays by the emission of beta radiation into the stable isotope Ba-137. This transition is completed either by direct conversion into stable Ba-137 (5.4 %) or via the metastable energy state of Ba-137m (94.6 %). 137 Cs has a very low rate of neutron capture and cannot yet be feasibly disposed of in this way unless advances in neutron beam collimation (not otherwise achievable by magnetic fields), uniquely available only from within muon catalyzed fusion experiments (not in the other forms of Accelerator Transmutation of Nuclear Waste) enables production of neutrons at high enough intensity to offset and overcome these low capture rates; until then, therefore, 137 Cs must simply be allowed Recommended Nuclear Decay Data Cs-137.

Further, all four measurements used coincidence counting to determine the electron emission In both cases, the decay of caesium 137 found in the body is much quicker than the natural radioactive decay with a period of 30 years. Even though caesium slowly enters the soil, the rapid decay of the activity in humans has made it unnecessary for the Belgians to decontaminate their soil: as they could do through treating with Prussian blue. However, primary fission products in the A 133 isobar chain have time to decay to stable 133 Cs during reactor operation and 134 Cs is produced by the reaction 133 Cs (n,γ) 134 Cs. Given the cooling time, the ratio between the decay rates of 134 Cs and 137 Cs can be used to estimate the burnup of fuel from a given reactor, see Figure 21.6 .
