What radiations can the RAD EYE detect and what capability does it have regarding the radiation source?

• A. Only gamma radiation
• B. Only neutron radiation
• C. Gamma and neutron; can identify source type
• D. No radiation detected

Answer: (C)

The key idea is that this device can sense two main kinds of radiation—gamma rays and neutrons—and it uses the patterns in both channels to infer what kind of radiation source is present. Gamma rays give energy-specific signatures that point to particular isotopes, while neutrons provide a different kind of signal that helps distinguish materials that might emit neutrons or that don’t produce gamma rays. By weighing the relative amounts, energies, and timing of the signals from both types, the RAD EYE can identify the source category—whether it’s a gamma emitter, a neutron source, or a combination. That dual-detection capability and the ability to classify the source type is what sets this option apart. If it only detected one type of radiation, or claimed no radiation at all, it wouldn’t offer the same source-identification capability.
