A source of nuclear data

The printed chart is nevertheless very useful for rapid assessment. For each element, there is the element symbol, atomic weight and thermal neutron absorption cross-section. Within the horizontal strip of isotopes, stable species are shown with a black background and contain the mass number, natural isotopic abundance of the 

The °Co square would be blue for (3 and contains the half-life, the major maximum beta energies in MeV (useful for bremsstrahlung estimation), major gamma energy (in keV) in order of emission probability and the thermal neutron cross-section. The isomer is shown as a white section with decay mode(s) and energies. On this particular chart, electron capture is shown as 8, isomeric transition as I and conversion electron emission as e , along with standard symbols. 

The chart contains sufficient information for simple calculations as to whether the quantities of radionuclides found are those that might be expected. The overall activation equation is

Longworth, G. (Ed.), (1998). The Radiochemical Manual, AEA Technology pic, HMSO, London, UK. Incorporates the NPL RSA(EXT)53 data and other data taken from the UKHEDD database. Includes the TECDOC-619 nuclides but does not incorporate the TECDOC-619 data. Superseded by DDEP and no longer recommended as a source of nuclear data. That does not diminish the value of this manual from a general informative point of view.
