1 The compressed package of electronic files con 1 The compressed package of electronic files contains the detailed data on the adult mesh-type reference computational phantoms (MRCPs). The package is organised in two folders: 'Phantom_data' and 'MC_examples'. 2 2 3 1. Data files in Phantom_data 3 1. Data files in Phantom_data 4 4 5 This folder is subdivided into two folders, on 5 This folder is subdivided into two folders, one for each of the two reference phantoms (AM: adult male, AF: adult female). Each folder contains the following files: 6 6 7 * Data files for tetrahedral mesh (TM) version 7 * Data files for tetrahedral mesh (TM) version of the adult MRCPs; the file names are: 8 MRCP_AM.node 8 MRCP_AM.node 9 MRCP_AM.ele 9 MRCP_AM.ele 10 MRCP_AF.node 10 MRCP_AF.node 11 MRCP_AF.ele 11 MRCP_AF.ele 12 The data files consist of NODE- and ELE-form 12 The data files consist of NODE- and ELE-format files. The NODE-format files contain a list of node coordinates composing the TM-version phantoms, with the following format: 13 - First line: <# of nodes> <dimension (= 3 13 - First line: <# of nodes> <dimension (= 3)> <n/a (= 0)> <n/a (= 0)> 14 - Remaining lines list # of points: <node 14 - Remaining lines list # of points: <node ID> <x> <y> <z> 15 The ELE-format files contain a list of tetra 15 The ELE-format files contain a list of tetrahedrons composing the TM-version phantoms and each tetrahedron is represented as four node IDs listed in the corresponding NODE-format files and an organ ID number with respect to the tetrahedron, and the format is as follows: 16 - First line: <# of tetrahedrons> <dimensi 16 - First line: <# of tetrahedrons> <dimension (= 3)> <# of attributes (= 1, for organ ID)> 17 - Remaining lines list # of tetrahedrons: 17 - Remaining lines list # of tetrahedrons: <tetrahedron ID> <node 1> <node 2> <node 3> <node 4> <organ ID> 18 18 19 * Data files for polygon mesh (PM) version of 19 * Data files for polygon mesh (PM) version of the adult MRCPs; the file names are: 20 MRCP_AM.obj 20 MRCP_AM.obj 21 MRCP_AM.mtl 21 MRCP_AM.mtl 22 MRCP_AF.obj 22 MRCP_AF.obj 23 MRCP_AF.mtl 23 MRCP_AF.mtl 24 These files consist of OBJ- and MTL-format f 24 These files consist of OBJ- and MTL-format files, which contain data on PM and colours, respectively. They can be imported in various 3D commercial programs such as 3ds Max (Autodesk, USA), MAYA (Autodesk, USA), Rapidform (INUS Technology Inc., Korea) and Rhinoceros (Robert McNeel, USA). 25 25 26 * Lists of the media, elemental compositions a 26 * Lists of the media, elemental compositions and densities; the file names are: 27 MRCP_AM_media.dat 27 MRCP_AM_media.dat 28 MRCP_AF_media.dat 28 MRCP_AF_media.dat 29 29 30 * The mass ratios of bone constituents (trabec 30 * The mass ratios of bone constituents (trabecular bone, red and yellow bone marrow) in the spongiosa regions; the file names are: 31 MRCP_AM_spongiosa.dat 31 MRCP_AM_spongiosa.dat 32 MRCP_AF_spongiosa.dat 32 MRCP_AF_spongiosa.dat 33 33 34 * The mass ratios of blood in various body tis 34 * The mass ratios of blood in various body tissues; the file names are: 35 MRCP_AM_blood.dat 35 MRCP_AM_blood.dat 36 MRCP_AF_blood.dat 36 MRCP_AF_blood.dat 37 37 38 * PDF files for phantom visualisation; the fil 38 * PDF files for phantom visualisation; the file names are: 39 MRCP_AM.pdf 39 MRCP_AM.pdf 40 MRCP_AF.pdf 40 MRCP_AF.pdf 41 The PDF files visualise the MRCPs in a 3D vi 41 The PDF files visualise the MRCPs in a 3D view. The PDF files can be opened in Acrobat program (Adobe Systems, San Jose, CA, USA) where one can navigate the phantoms in detail, e.g. by rotating or enlarging each of the organ/tissue models. Detailed instruction on these 3D PDF files can be found elsewhere (https://helpx.adobe.com/acrobat/using/displaying-3d-models-pdfs.html). 42 42 43 2. Data files in MC_examples 43 2.

Each of the compressed files include examples for internal and external exposures, where the source is defined as homogeneous liver source and a point source located at 1 m in front of the phantom, respectively, both emitting 1-MeV photons. Detailed information on the implementation is described in the 'README.txt' file included in each compressed file. Please note that neither the ICRP nor Task Group 103 shall not be liable for any result produced by any of these input examples.
