Morphology
nonradioactive = radioactive (transparent) = non + radioactive
The productive prefix 'non' simply negates the adjective 'radioactive', yielding a clear 'not radioactive' meaning.
Etymology
Nonradioactive begins with non- meaning 'not' and the rest comes from radio-, a root about 'rays' or 'radiating', as in radiate. So nonradioactive is easy to remember as 'not giving off rays', which is why it means 'not emitting harmful radiation'.
