Abstract: XMuDat is a program to be used with Windows 95 or Windows
NT for the presentation and calculation of various photon interaction coefficients. Six
absorbing materials can be set up individually. Each material can be composed of
components chosen from the elements and further from a number of compounds and mixtures of
dosimetric interest. Data for mass attenuation-, mass energy transfer- and mass energy
absorption coefficients in a photon energy range of 1 keV to 50 MeV can be retrieved.
A set of two diskettes with XMuDat files is available upon request, costfree, from
the IAEA Nuclear Data Section. Users with access to Internet may download xmudat.zip file (1,174 KB) from

Note:
The IAEA-NDS-reports should not be considered as formal publications. When a
nuclear data library is sent out by the IAEA Nuclear Data Section, it will be accompanied
by an IAEA-NDS-report which should give the data user all necessary documentation on
contents, format and origin of the data library.
IAEA-NDS-reports are updated whenever there is additional information of relevance to the
users of the data library.
For citations care should be taken that credit is given to the author of the data library
and/or to the data center which issued the data library. The editor of the
IAEA-NDS-report is usually not the author of the data library.
Neither the originator of the data libraries nor the IAEA assume any liability for their
correctness or for any damages resulting from their use.

Citation guideline:
When quoting a computer-based data library in a publication it is recommended
- to give first the print reference in which the author(s) describe(s) the generation of
the data,
- to give thereafter the database reference which contains the numerical data, including
the version of the database,
- and then to mention the data center or the online service from which the data were
received.

XMuDat is a program to be used with Windows 95 or Windows NT for the presentation and calculation of mass attenuation, mass energy transfer and mass energy absorption photon coefficients for total or specific reaction channels.
Two data sources can be used for generation of photon interaction coefficients:
[1]. J M. Boone, A E. Chavez; Medical Physics 23, 12 (1996) 1997-2005.
[2]. J H Hubbel, S M Seltzer; Tables of X-Ray Mass Attenuation
Coefficients and Mass Energy-Absorption Coefficients 1 keV to 20 MeV for Elements Z=1 to
92 and 48 Additional Substances of Dosimetric Interest. NISTIR 5632, 1995
(also at: http://physics.nist.gov/PhysRefData/XrayMassCoef/cover.html).
The source of the data which can be selected for retrieval of the coefficients is given in Table below.
Total | Photo- electric | Rayleigh scattering | Compton scattering | Pair production | Triplet production | |
Mass attenuation coefficient | [1] or [2] | [1] | [1] | [1] | [1] | [1] |
Mass energy-transfer coefficient | [1] | [1] | =0.0 on definition | [1] | [1] | no |
Mass energy-absorption coefficient | [1] or [2] | [1] | =0.0 on definition | [1] | [1] | no |
Six absorbing materials can be set up individually. Each material can be composed of components chosen from the elements (Z=1 to 92) and further from 200 compounds and mixtures of dosimetric interest. Data for mass attenuation-, mass energy transfer- and mass energy absorption coefficients in a photon energy range of 1 keV to 50 MeV can be retrieved. The energy range is limited by the interest of the medical physics community.
All retrieved data can be printed in tabular format or plotted.
