Okay, the user wants me to translate "non-radiant" into Japanese. Let me think about the correct term here. "Non-radiant" can mean not emitting light or not shining. In Japanese, the adjective for radiant is "放射線の" or "光輝く", but "non-radiant" would be the opposite.
So, the direct translation might be "非放射性" if referring to non-radioactive, but the user might be talking about something not emitting light. In that case, "非発光性" could be an option. However, "non-radiant" is more commonly translated as "非放射性" when discussing radiation, like in materials or substances.
Wait, the user didn't specify the context. But since the previous interaction was about translation rules, maybe they just want a direct translation. Let me check if "non-radiant" is a standard term. In some contexts, like describing a person's appearance, "non-radiant" might be "無輝き" or "輝きのない". But without context, the safest bet is "非放射性" as the direct translation.
Alternatively, maybe "非発光" is another possibility. But I should stick to the most common translation. Let me confirm with a dictionary. "Non-radiant" as an adjective: the Japanese equivalent would be "非放射性" (hikashi-sei) for non-radioactive, but if it's about not emitting light, then "発光しない" or "非発光性".
Hmm, the user might be looking for the general term. Since the original instruction was to translate all content into Japanese, and the input is "non-radiant", the best translation would be "非放射性". I'll go with that unless there's more context, which there isn't. So the answer is "非放射性".
非放射性
