Extremely low frequency and radiofrequency surveys
The NRL staff have made many measurements of exposures to ELF electric and magnetic fields, and RF fields. A selection of results from measurement surveys is presented here in order to make this information more widely available.
Although many of these results present exposure data from particular sites, this information can be used to get some idea of what the exposures might be around a similar installation in another part of the country.
