Question 73 Deck Safety
70% to passWhich statement concerning exposure to radiation is TRUE?
A
The INMARSAT unit's ray dome filters out potentially dangerous UV rays.
B
Certain INMARSAT systems will automatically transmit when called and can expose an individual to harmful radiation.
C
An INMARSAT-C antenna must be carefully avoided because it focuses the transmitter's signal into a fine beam of energy.
D
INMARSAT-A and B antennas are safe because they are omnidirectional.
AI Explanation
The correct answer is B. Certain INMARSAT systems can automatically transmit when called, exposing individuals to potentially harmful radiation. INMARSAT-C terminals, in particular, focus the transmitter's signal into a fine beam, which can pose a radiation risk if not handled properly. In contrast, INMARSAT-A and B antennas are omnidirectional and generally considered safer. The INMARSAT unit's ray dome does not filter out UV rays, so answer A is incorrect. Answer C is also incorrect, as the INMARSAT-C antenna's focused beam is the source of potential radiation exposure, not the antenna itself.
