Final answer:
The EOMS is a solid-state radiation detector that passively detects and converts in-band radiation into electrical signals, and sends them to the ECU.
Step-by-step explanation:
The subject of this question is Physics. The EOMS, or solid-state radiation detector, is a device made of semiconductors that passively detects and converts in-band radiation into electrical signals. These signals are then sent to the ECU.
