Handbook description

Particular emphasis is placed on the methodical combination of the normative fundament of isotope decay-scheme with the decay structures in a new developed list-mode by the author, including:

  • half-life, q-values, references, uncertainties

  • Alpha-, Beta(-/+)-, EC-, IT-, sf-branches, energies & emission-probabilities as well for photons & x-rays

  • energy-lists in intensity order with gray highlighted fields for energy interference for alpha’s

  • cascade decays (level-population), crossover transitions, summing & escape energies as well coincidence & random summing,

but also a lot of additional information to the properties of isotopes as abundance, natural activity, activation, isotope production, etc. from the latest available nuclear data bases. The Handbook provides not only in-depth knowledge on decay information but also for the wide-field of n-interaction/activation occurring on nuclear power plants, on air components, on selected light isotopes as well as on cosmic induced radiation and observable photons produced in commonly used shielding, mounting and detector materials for lowest-background application. Isotopes helpful for indication or evidence of activation as Ag-106, Rh-102 and fission as I-130 are displayed.

Main Updates 2023

Extended and Revision

  • The decay sequences Ce-/La-134 (PET-Isotopes), Ba-/Cs-131 (activation products), Zr/Nb-93-95-97 as well Mo-93, Nd-93m, Sr-91, Te-131m/131, Cd-115m/115 (fission products), but also the activation products Ag-106m/106, Rh-102m/102, Rb-84, Sb-120, Au-196, Tm-168 und W-187 have been inserted begin of 2023.

  • Extention of energy/isotope lists to ~4700 entries from all radioisotopes from the "Radionuclide Handbook" (~310 isotopes), inclusive SE, DE, XE, RS & CS effects, radioisotope production and additional information, has been prepared into the separate "Energy/Isotope Tabels".

  • The natural x-ray energies and intensities are elaborated and extended as well as implemented in the analysis software VRF for high resolution photon spectrometry.

  • Complete revision of the subcharpter "Cosmogenic Produced Radioisotopes", "PET Positron Emitter" but also "Bone Seeking" and "Body Composition".

  • Selected Radioisotopes such as I-130 (blocked fission product), produced only direct through fissison therefore used for spallation evidence for nuclear forensics, we have designated.

  • For the direct detection of beta radiation selected standard calibration isotopes such as Beta- & CE emitter are now implemented on a separate page.

  • The stable or extremely long-lived isotopes Te & Xe - decaying only via  two beta's or two EC - we have completed in subchapter "Iodine's".

  • In general, the latest available data are updated until July 2023 - selected from NNDC(NDS), BIPM(LNHB/LNE), IAEA and NP for each radioisotope.
