Answer
Contamination
Explanation
This question is querying the correct term for the state of an object that contains unwanted radioactive materials. The four options provided are "nuclear", "[ALL of these]", "contamination", and "irradiation". Looking at these options and based on knowledge about radioactivity, the idea of unwanted radioactive substances residing in an object captures the concept of "contamination", a term widely used in discussions about handling and disposing of radioactive materials. "Irradiation", which refers to the process of exposing an object to radiation, does not accurately describe the situation. Being "nuclear" just denotes having to do with the nucleus of an atom, so it doesn't specifically describe the presence of unwanted radioactive materials either. So, the correct term in this context would be contamination.
