Which measure most effectively minimizes RF exposure in a work area?

Minimizing RF exposure is achieved by applying the hierarchy of controls, with engineering and administrative measures delivering the strongest protection. The most effective approach is to increase distance from the RF source, use shielding to attenuate the field, and limit the time spent near the source. These factors reduce both the instantaneous field strength and the cumulative dose a worker receives. Personal protective equipment cannot guarantee complete protection on its own because RF energy can couple through clothing, there can be gaps in coverage, and some exposures are too intense for PPE to handle. Relying on PPE alone leaves significant exposure risk, and increasing time near RF sources or ignoring warnings only raises the danger.
