Radiological characterization of components in accelerator environments is often required to ensure adequate radiation protection during maintenance, transport and handling as well as for the selection of the proper disposal pathway. The relevant quantities are typical the weighted sums of specific activities with radionuclide-specific weighting coefficients. Traditional methods based on...

20. ActiWiz3 – an overview of the latest developments and their application

Dr Christian Theis (CERN)

In 2011 the ActiWiz code was developed at CERN in order to optimize the choice of materials for accelerator equipment from a radiological point of view. Since then the code has been extended to allow for calculating complete nuclide inventories and provide evaluations with respect to radiotoxicity, inhalation doses, etc. Until now the software included only pre-defined radiation environments...

62. Strategy of Instrument Shield at Spallation Source - experiences at J-PARC

Masatoshi Arai (European Spallation Source ERIC)

22/05/2017, 15:20

Neutronics calculation is a key component to design radiation facility. There are well established and reliable codes for radiation transportation calculation, such as MCNPX, GEANT4, PHITS, etc. Shielding design to keep the dose rate lower than regulation is of the main importance. However, at neutron scattering facility radiation will not be contained just within a shield of source,...
