Okay, the user wants me to translate "radio-nuclide" into Indonesian. Let me check the rules again. The first rule says to translate all content into Indonesian. The second rule states that if the content is already in Indonesian, leave it as is. The third rule is to provide only the translation without explanations.
So, "radio-nuclide" is an English term. I need to find the correct Indonesian equivalent. The term "radio-nuclide" refers to a nuclide that is radioactive. In Indonesian, "nuclide" is often translated as "nuklida," and "radio-" would be "radio-" as a prefix. So combining them, it should be "nuklida radioaktif." Wait, but sometimes technical terms are kept in English in Indonesian contexts. However, the user's instruction is to translate, so I should provide the Indonesian translation. Let me confirm: "radio-nuclide" is a compound term. The correct translation would be "nuklida radioaktif" or "nuklida radio." But "radio-nuclide" specifically refers to a radioactive nuclide, so "nuklida radioaktif" is more accurate. Alternatively, "nuklida radio" might be used, but I think "nuklida radioaktif" is the standard term in Indonesian scientific literature. I'll go with that.
