“Data for Shield Calculation of Radiation Facilities (2015)” are widely used as reference for shielding calculations of radiation facilities. This report provides the data of additional 85 radionuclides of which importance is increasing recently, while they are not included in the data book. The effective-dose transmittance of photons emitted from these nuclides were calculated. For the nuclides which show radioactive equilibrium, the progeny nuclides were included in the calculation, considering the usage conditions. The calculations were performed with following shielding materials: lead, tungsten, iron, copper, concrete, and water.

Key words: effective-dose transmittance; 85 radionuclides; lead; tungsten; iron; copper; concrete; water
