ICRP Publication 107: Nuclear Decay Data for Dosimetric Calculations
New to This Edition
In this report, the Commission provides an electronic database of the physical data needed in
calculations of radionuclide-specific protection and operational quantities. This database supersedes the
data of Publication 38 (ICRP, 1983), and will be used in future ICRP publications of dose coefficients for
the intake of or exposure to radionuclides in the workplace and the environment.
The database contains information on the half-lives, decay chains, and yields and energies of radiations
emitted in nuclear transformations of 1252 radionuclides of 97 elements. The CD accompanying the
publication provides electronic access to complete tables of the emitted radiations, as well as the beta and
neutron spectra. The database has been constructed such that user-developed software can extract the data
needed for further calculations of a radionuclide of interest. A Windows-based application is provided to
display summary information on a user-specified radionuclide, as well as the general characterisation of
the nuclides contained in the database. In addition, the application provides a means by which the user can
export the emissions of a specified radionuclide for use in subsequent calculations.
