GEANT4 validation for X-ray treatment of wooden cultural heritage artefacts

The preservation of cultural heritage is very important. Ionizing radiation is widely used for this purpose and use of gamma irradiation has become common practice in cultural heritage preservation. The number of available electron accelerators is two orders of magnitude greater than for gamma facilities, and many countries do not have gamma facilities. In this work we demonstrate the possibility of using an electron accelerator and X-rays generated from accelerated electrons for radiation treatment of wooden cultural heritage. The GEANT4 toolkit was used for the simulation of the passage of particles through matter. The accuracy of radiation treatment numerical simulation in comparison with experiment was in range of 1.5-11.8%.
