openmc.data.dose_coefficients(particle, geometry='AP', data_source='icrp116')[source]

Return effective dose conversion coefficients.

This function provides fluence (and air kerma) to effective or ambient dose (H*(10)) conversion coefficients for various types of external exposures based on values in ICRP publications. Corrected values found in a corrigendum are used rather than the values in the original report. Available libraries include ICRP Publication 74 <https://doi.org/10.1016/S0146-6453(96)90010-X> and ICRP Publication 116 <https://doi.org/10.1016/j.icrp.2011.10.001>.

For ICRP 74 data, the photon effective dose per fluence is determined by multiplying the air kerma per fluence values (Table A.1) by the effective dose per air kerma (Table A.17). The neutron effective dose per fluence is found in Table A.41. For ICRP 116 data, the photon effective dose per fluence is found in Table A.1 and the neutron effective dose per fluence is found in Table A.5.

Parameters

  • particle ({'neutron', 'photon', 'photon kerma', 'electron', 'positron'}) – Incident particle

  • geometry ({'AP', 'PA', 'LLAT', 'RLAT', 'ROT', 'ISO'}) – Irradiation geometry assumed. Refer to ICRP-116 (Section 3.2) for the meaning of the options here.

  • data_source ({'icrp74', 'icrp116'}) – The data source for the effective dose conversion coefficients.

Returns

  • energy (numpy.ndarray) – Energies at which dose conversion coefficients are given

  • dose_coeffs (numpy.ndarray) – Effective dose coefficients in [pSv cm^2] at provided energies. For ‘photon kerma’, the coefficients are given in [Sv/Gy].
