  • EURADOS-Working-group

    Membership

    Working Group 6 has:

    • 34 full members from 13 countries
    • 20 corresponding members

Motivation

Computational methods are indispensable tools in the field of radiation dosimetry, with a wide variety of applications ranging from simulation of the response of radiation detectors, simulation of radiation transport in complex geometrical setups to obtain the radiation fluence at a region of interest, to the assessment of dose quantities in exposed humans. A large variety of computer codes are available for these purposes of which many have developed to versatile, easy-to-use tools for ‘everybody’ while others require more expertise already in their operation.

 

Aim of working group:

Promoting good practice in the field of computational methods in radiation dosimetry for radiation protection and applications in radiation medicine

WG6 will contribute by:

As a pool of European expertise in this field, Working Group 6 promotes good practice in the field of computational methods in radiation dosimetry for radiation protection and applications in radiation medicine. It carries out scientific research and development as well as knowledge transfer activities in the area of computational dosimetry. While Monte Carlo simulations are the dominant method, other aspects of computational dosimetry such as spectra unfolding or the proper use of voxelized geometrical models are also considered.

The focus on techniques rather than scientific topics implies a cross-sectional role of WG6 and collaboration with other EURADOS WGs, covering a large number of up-to-date topics in radiation dosimetry. Furthermore, knowledge transfer on the competent use of Monte Carlo codes and other computational techniques by training courses and comparison exercises are key aspects of the WG6 scope.
