Question 125Deck Safety70% to pass

Which statement concerning exposure to microwave signal radiation is TRUE?

AI Explanation
The correct answer is D. The INMARSAT-B ray dome normally prevents nearby persons from being able to determine the direction of the internal antenna, which means there is a potential hazard from microwave signal radiation. This is because without being able to identify the direction of the antenna, people may inadvertently expose themselves to the microwave signal. The FCC regulations require that radiated power be kept to a minimum, but the ray dome can obscure the antenna's orientation, creating a potential hazard. The other answer choices are incorrect because they do not accurately describe the hazard potential or regulatory requirements for INMARSAT antenna systems.
