Okay, the user wants me to translate "non-radical" into Traditional Chinese. Let me check the rules again. The first rule says to translate all content into Traditional Chinese. The second rule states that if the content is already in Traditional Chinese, output it unchanged. The third rule is to provide only the translation result without explanations.
So, the input here is "non-radical". Since it's in English, I need to translate it. The term "non-radical" can be translated as "非激進" in Traditional Chinese. I should make sure there's no existing Traditional Chinese text here, which there isn't. So the correct translation is "非激進". I'll just output that without any extra text or explanations.
