Answer
1: irradiation; 2: does NOT
Explanation
The statement addresses a common concept in physics, nuclear radiation and its effects on objects. Radioactivity describes the characteristic of certain materials to emit ionizing radiation or particles caused by the spontaneous disintegration of atomic nuclei. Within this context, the two terms to be addressed are "irradiation" and "contamination." The primary confusion arises when trying to differentiate the two terms, given that they are a cause of concern for radioactivity. If we break it down: 1- Irradiation refers to the exposure of an object to nuclear radiation. However, it is crucial to know that in the process when an object is subjected to irradiation, even though the object is exposed to the radiation, it itself does not become radioactive. 2 - On the other hand, Contamination is when radioactive material is deposited on or in an object or a person. If an object is contaminated by a radioactive material, then it probably would be considered as radioactive since it has radioactive atoms on or within it. From the foregoing explanation, it becomes evident that 'exposing an object to nuclear radiation' reflects the term "irradiation", and after this radiation treatment, the initially irradiated object 'does not become radioactive'. These wooden shoes are illuminated by irradiation but do not become contaminated and, therefore, continue to be related to radiation.
