At what frequency range does the human body absorb RF energy most effectively?

The human body absorbs RF energy most effectively in the frequency range of 40-90 MHz due to its biological properties and the resonance of body tissues with those frequencies. At these frequencies, the energy from radiofrequency radiation is optimally absorbed by the ions and molecules within the body, leading to heightened interaction and absorption rates.

This frequency range coincides with certain wavelengths that are effective in penetrating body tissues without excessive reflection or scattering. The liquid content in body tissues, primarily water, has a natural resonance that aligns with these RF frequencies, which enhances energy absorption and can contribute to biological effects.

Understanding the physiological aspects of RF absorption is crucial for evaluating potential health impacts and implementing safety measures in environments where exposure to RF radiation exists, especially in the context of occupational health and safety for industrial hygienists.
