Abstract

Updated evaluations of the half-lives and prominent gamma ray intensities have been presented for 20 radionuclides – dosimetry reaction residuals. The new values of these decay characteristics recommended for the IRDFF library were obtained using the approaches and methodology adopted by the working group of the Decay Data Evaluation Project (DDEP) cooperation. The experimental data published up to 2014 were taken into account in updated evaluations. The list of radionuclides includes ³H, ¹⁸F, ²²Na, ²⁴Na, ⁴⁶Sc, ⁵¹Cr, ⁵⁴Mn, ⁵⁹Fe, ⁵⁷Co, ⁶⁰Co, ⁵⁷Ni, ⁶⁴Cu, ⁸⁸Y, ¹³²Te,¹³¹I, ¹⁴⁰Ba, ¹⁴⁰La, ¹⁴¹Ce, ¹⁸²Ta, ¹⁹⁸Au.
