A tibble with 32 variables, 31 original variables from ICRP, plus the derived decay_constant variable.

RN Name of nuclide; e.g. Am-241, Tc-99m half_life Half-life of nuclide. Caution - units vary. units Half-life units: ls, microsecond; ms, millisecond; s, second; m, minute; d, day; y, year decay_mode A, alpha; B-, beta minus; B+, beta plus; EC, electron capture; IT, isomeric transition; SF, spontaneous fission pointer_rad Not functional. Originally, location of nuclide in the ICRP_07.RAD file pointer_bet Not functional. Originally, location of nuclide in ICRP_07.BET file pointer_ack Not functional. Originally, location of nuclide in ICRP_07.ACK file pointer_nsf Not functional. Originally, location of nuclide in ICRP_07.NSF file progeny_1 Radioactive progeny number 1 pointer_1 Location of progeny number 1 in RN dataset branch_1 Branching fraction to progeny number 1 progeny_2 Radioactive progeny number 2 pointer_2 Location of progeny number 2 in RN dataset branch_2 Branching fraction to progeny number 2 progeny_3 Radioactive progeny number 3 pointer_3 Location of progeny number 3 in RN dataset branch_3 Branching fraction to progeny number 3 progeny_4 Radioactive progeny number 4 pointer_4 Location of progeny number 4 in RN dataset branch_4 Branching fraction to progeny number 4 E_alpha Energy of alpha emissions (MeV/nuclear transformation) E_electron Energy of electrons, including beta (MeV/nuclear transformation) E_photon Energy of photon emission (MeV/nuclear transformation) num_phot_lt_10k Number of photons of energy less than 10 keV num_phot_gt_10k Number of photons of energy greater than 10 keV num_betas Number of beta transitions num_mono_e Number of mono-energetic electrons num_alpha Number of alpha transitions AMU Atomic mass of radionuclide (Audi et al., 2003) air_kerma_rate_const Air-kerma rate constant (Gy-m^2/Bq s) air_kerma_coef Point source air-kerma coefficient (Gy-m^2/Bq s) decay_constant Decay constant in inverse seconds.
