Abstract

DIN-6847 is the most suitable standard to estimate shielding requirements in medical radiotherapy installations using linear electron accelerators. Its calculation method is based on the tenth-value thickness concept for which values given by curves and tables are recommended in DIN-6847. These parameters have been estimated for both primary and secondary X-ray beams using the MCNP code based on the Monte Carlo method. Results show that DIN-6847 values are conservative for secondary X-ray beam, but not always for direct radiation. The methodology used has been tested using the mentioned code and results are consistent
