What is the minimum distance for personnel for Radiation Hazard - V/UHF-1 & 2?

• A. 3 feet
• B. 15 feet
• C. 130 feet
• D. 50 feet

Answer: (A)

Maintaining the proper safe distance from RF radiation hazards around V/UHF transmitters is what this question tests. For the V/UHF-1 and V/UHF-2 units, the area where RF exposure could exceed permissible limits is kept to a very close radius, so the minimum distance you must observe is 3 feet. Staying at least this far away ensures you remain outside the portion of the field where exposure could approach or exceed the allowable limits for personnel during normal operation.

The 3-foot distance comes from the transmitter’s power level and antenna configuration, which define a safe boundary based on established exposure standards. Larger distances, like 15, 50, or 130 feet, would be more than necessary for typical operation of these units and would unnecessarily restrict access, except in special maintenance scenarios or if the equipment is operated at higher power or with different antennas. In practice, if maintenance is performed or if the transmitter is energized at higher power, procedures would dictate how to approach or further restrict access, but for normal use the 3-foot minimum applies.
