NIR has a low energy (10 eV) and simply succeeds in inducing vibrations in molecules and causing heating effects. Exposure to ELF magnetic and electrical fields has biological consequences. Nonetheless, excluding areas large enough to stimulate existing densities higher than the edge for nerve tissue stimulation, there is no consensus on whether these influences pose a risk to human health. Because magnetic fields are more destructive than electrical fields, a limit of 0.2–0.3 T or 2.5 mG, which is internationally recognized as a benchmark level in several countries, must be established at both the occupational and residential levels. The accepted value for an electric field is 25 V/m.The highest recommended limit for body radiation is 10 mW/cm², 195 V/m in the United States and 0.1 mW/cm², 20 V/m in the CIS. Human-made electric and magnetic fields (typically 25 V/m and 2.5 mG or 0.25 T) are significantly higher than natural electric and magnetic fields of 10^-4 V/m and 10^-13 T, respectively.The radiated power limit from high frequency sources, as suggested by the International Commission on Non-Ionizing Radiation Protection (ICNIRP): April 1998/IEEE C95.1/Council Recommendation 1995/519/EC, is different for high frequency radio waves. These figures differ depending on the range. For example, at 950 MHz (42 V/m, 4.75 W/m²) and 1850 MHz (59 V/m, 9.25 W/m²), the voltages are 42 V/m and 4.75 W/m², respectively. Due to rapidly decreasing EM fields in the cell phone antenna near-field area, the basic absorption rate (SAR) decreases by 10^–15 percent for each millimeter cell phone separation, according to measurements and software simulations.Lower animals have been discovered to be extremely sensitive to EMFs. In the wild, animals like rats and bees have been observed using NIR/EMF to defend themselves and their young.
