Photon, electron, proton and neutron interaction data for body tissues
This Report provides specific information on representative sets of tissues that illustrates the effects of tissue composition variation on some pertinent radiation interaction quantities. It includes photon (10 key to 100 MeV), electron (10 key to 100 MeV), proton (1 to 500 MeV) and neutron (25 MeV to 30 MeV) interaction data for body tissues, covering the age interval from fetus to adult. The interaction data presented here supplement the earlier tabulations, but for the sake of completeness and clarity the results for adult tissues are repeated. Soft tissues, skeletal tissues and calculi are considered. Soft tissues include adipose tissue, brain, breast (including component tissues), heart, liver and muscle (skeletal). Skeletal tissues and calculi include cortical bone, breast calcifications, cholesterol gallstones and various types of urinary (renal) stones. For each body tissue or group of tissues, the available compositions appropriate to fetal, infant, child and adult are used. Data for a small selection of diseased soft tissues are included. The Report is structured into three sections and two appendices. Definitions and specifications of the interaction coefficients and dosimetric quantities used in the Report are given in the next part of this Section. The composition of body tissues is discussed in Section 2. Details of the methods adopted for the calculation of the interaction data are given in Section 3. The elemental compositions, mass and electron densities of the complete set of body tissues are listed in Appendix A. Photon, electron, proton, and neutron interaction data are given in the concluding Appendix.
