Millimeter waves (MMW) are a type of electromagnetic radiation with wavelengths between 1 millimeter and 10 millimeters, corresponding to frequencies in the range of about 30 GHz to 300 GHz. While it's true that certain high-energy forms of electromagnetic radiation can penetrate materials to various extents, the millimeter waves used in 5G technology operate at significantly lower power levels, which affects their interaction with materials.
Here are some key points regarding the safety and behavior of millimeter waves in the context of 5G:
1. **Power Levels**: The millimeter waves used in 5G communications are transmitted at relatively low power levels, much lower than those that would be required to penetrate solid materials like rock. For example, the power levels employed in 5G networks are designed to safely communicate information over short distances, typically within urban environments.
2. **Penetration Characteristics**: Millimeter waves can penetrate certain materials (like clothing or the outer layers of skin) to a limited extent, but they are generally absorbed by larger, denser materials (like walls or rock) rather than penetrating them deeply. This makes them effective for high-speed data transmission over short ranges without causing significant interference from many physical barriers.
3. **Safety Standards**: Regulatory bodies, such as the Federal Communications Commission (FCC) in the United States, have established safety guidelines for exposure to radiofrequency electromagnetic fields, including those used in 5G technology. These standards are based on extensive scientific research and consider exposure levels that are safe for humans.
4. **Ongoing Research**: Research into the effects of millimeter waves on human health continues, and regulatory agencies review new findings to ensure public safety. So far, studies have not found evidence of harmful effects from the MMW used in 5G at the exposure levels typical in public environments.
In summary, while millimeter waves have interesting properties and can penetrate certain materials, their use in 5G is designed to be safe and effective for communication purposes, with power levels that are far below those that would pose health risks or allow for significant penetration of more substantial materials such as rock.
