Abstract

Overview

The study examines the implications of increased electromagnetic fields, particularly with the advent of 5G networks. It raises public health concerns about prolonged exposure and investigates the efficacy of different shielding materials to mitigate these risks.

Shielding Materials & Methods

The research assesses the shielding effectiveness of two materials: a traditional brick wall and a specially designed shielding fabric. The study spans a frequency range from 1 GHz to 9 GHz, providing a comprehensive view of their protective capabilities across these frequencies.

• Brick Wall: Analyzed with a thickness of 33cm, showing varying efficiency up to 5.5 GHz.
• Shielding Fabric: Comprised of 68% cotton, 16% polyester, and 16% stainless steel, attached to polystyrene. Consistent effectiveness across the tested frequencies.

Findings

Results indicate that both materials prevent EMF penetration to some extent. The brick wall's effectiveness increases with frequency but plateaus at higher frequencies, while the shielding fabric shows uniform protection throughout the range tested.

Conclusion

The study concludes that the shielding fabric offers more reliable protection against electromagnetic fields compared to the brick wall and can be a practical choice for environments with a high prevalence of electromagnetic sources. Protective strategies including these materials are crucial for minimizing health risks associated with EMF exposure.
