Introduction: In this study, ZnO/Acrylamide composites were considered as gamma and x-ray shielding. The mass attenuation coefficient and half value layer for the bulk of ZnO and various percentages of the ZnO composites were calculated for different range of energy.

Materials and methods: In this paper, the Monte Carlo N-Particle eXtended (MCNP-X) version 2.4.0T was used as a tool for determining the mass attenuation coefficient and vale layer of the shielding samples.

Results: The obtaining data were in good agreement with the data that were come from the X-COM program. Also, the data show that the composite's ability in attenuation of the gamma rays is similar to the bulk of ZnO.

Conclusion: The results show the preferences of using composites as a radiation shielding in comparison with the bulk of the ZnO.
