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 http://www-nds.iaea.org/reports/nds-195.htm .

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.

The source of the data which can be selected for retrieval of the coefficients is given in Table below.

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.
