Who needs an RF Hazard Assessment?

FCC licensees, building managers, site managers, construction companies, anyone who has people exposed to Radio Frequency Emissions.

​

An RF hazard assessment or NIER Report, at any site with rf is very involved and requires the person performing the assessment to be trained, competent, and qualified to perform the assessment. The assessor must have some basic knowledge of the site prior to showing up on the site so that the proper equipment is taken to the site.

​

Some equipment may have a limited frequency range, while some may be very directional. Most RF probes are for use at communication sites are field dependent as well. At sites with transmitters below 300 MHz both the magnetic and the electric field must be measured due to the fact that either  one could be dominant. In addition the site must be assessed for induced and contact current hazards.

The best equipment on the market today can have as much as 4 db of error. These items can in some cases be addressed and mitigated with proper training. Some of the other equipment could have as much as 30 db of error in complicated environments. As discussed earlier a personal protection monitor can be used for a limited hazard assessment. Prior to this being done the site must go through an extensive hazard assessment with the proper measurement equipment that will show actual RF levels at the site.
