Epcard


EPCARD is a software program that calculates radiation exposure of aircrews. The software code is based on the FLUKA transport code. EPCARD allows calculation of a simulated dose from most important components of penetrating cosmic radiation on any aviation route and for any flight profile at altitudes from 5 to 25 km.
Epcard helps airlines monitor radiation exposure, and comply with regulations relating to this area.

Development

This software package was developed by scientists of the Institute of Radiation Protection of the Helmholtz Zentrum München, German Research Center for Environmental Health with support from the European Commission and University of Siegen, Germany.

Simulation of radiation exposure

The EPCARD program virtually simulates a flight in the “quasi-real” radiation field of cosmic secondary particles. It is based on the energy spectra of neutrons, protons, photons, electrons, positrons, muons, and pions, calculated by means of the FLUKA Monte Carlo code at various altitudes in the Earth’s atmosphere down to sea level, for all possible physical parameters of solar activity and geomagnetic shielding conditions. A large scale set of “fluence-to-dose” conversion coefficients is employed, to calculate dose quantities in terms of ambient dose equivalent, H*, and effective dose, E. EPCARD.Net is based on the same physical algorithms as the EPCARD program, but is currently ready to process some extended physical parameters giving more precise information about flight route doses. EPCARD.Net is a completely new code which can be run on many systems such as Microsoft Windows NT/2K/XP/Vista or ‘UNIX kernel type’ operating systems like Linux, Mac OS X or Solaris.

Approval

The Luftfahrt-Bundesamt and the Physikalisch-Technische Bundesanstalt granted official approval for EPCARD version 3.34 in December 2003. EPCARD.Net Professional version 5.4.3 was approved for official use for aircrew dose assessment by LBA and PTB in April 2010.

Usage

Among the users of the software include major German airlines like Lufthansa, Condor Flugdienst, LTU International or the international airline service provider ASISTIM GmbH.
Free of charge on-line dose calculations for any flights can be performed with a simplified version of EPCARD, on the EPCARD web site.
