The International Commission on Non-Ionizing Radiation Protection (ICNIRP) publication Guidelines for Limiting Exposure to Time-Varying Electric and Magnetic Fields (1 Hz to 100 kHz) sets out limits for exposure to ELF fields. The limits are based on careful review of the research into the health effects of exposure to ELF fields. The Brown University ELF safety program follows these guidelines (limits). Research has been done over the past 30 years to find out if the ELF fields produced by electrical and power lines could be harmful.
