Radiation Dose Deposition in the Active Marrow of Reference Man.
Abstract
Dose Deposition in the active bone marrow of reference man was calculated using the MORSE Monte Carlo transport Code in the adjoint mode. Calculations were made in a three region reference man phantom described in Combinatorial Geometry. Calculations were performed using cross sections and KERMA factors from the 37 neutron-21 gamma ray group DNA Few Group Library. KERMA factors used in the calculation of dose were those for the constituents of active marrow alone for neutron dose and active marrow plus trabecular bone constituents for photon dose. Dose deposition (or response) functions (rad (marrow) per unit incident radiation fluence) are tabulated in energy differential and angle integral and differential form for gamma ray dose from incident gamma rays and for neutron and gamma ray dose from incident neutrons. Tabulations are for eight skeletal regions and for reference man. The dose deposition factors have been used to determine marrow dose from hypothetical contemporary weapon types and for Little Boy and Fat Man.
