Extended Abstract: Modifications of shielding construction materials based on Portland cement with the addition of powder nanomaterial shungite were developed. Attenuation and reflection of electromagnetic radiation for obtained materials were studied. Recommendations for using are given.
Key words: construction materials, shungite, screening, reflection coefficient, attenuation.
