Which of the following types of equipment are exempt from RF exposure evaluations?

In 2021, the FCC updated its rules regarding RF exposure limits, eliminating many of the previous categorical exemptions that were based strictly on a station's power output and operating frequency. However, to avoid placing an unreasonable retroactive burden on amateurs and manufacturers, the FCC implemented a grandfathering clause. Hand-held transceivers sold prior to May 3, 2021, remain exempt from these newer RF exposure evaluation requirements. The other options list arbitrary power limits (like 7 watts), specific antenna sizes, or near-field radiation rules that do not exist under the current FCC RF safety guidelines.
