What precautions have been taken to prevent microwave radiation leaks?
First, it should be made clear that microwave “radiation” is a misnomer. No ionizing radiation is propagated by the microwave system. The microwave operating frequency is actually an ultra high frequency (UHF) radio frequency, as specified by the U.S. Federal Communications Commission (FCC). Secondly, no measurable amount of microwave energy has been detected near the biosolids entry or exit tables, around any access doors, or near any micro- wave entry port flanges. Choke pin trips and choke flange doors effectively ground all microwave energy in the entry/exit and access door areas, respectively. Microwave entry port flanges are sealed with a microwave-absorbing gasket.
