Question

particular care must be taken when using radiation for medical imaging. this is the result of radiation’s ability to create ______ in human tissue and possible biochemical changes.

○ ionizations
○ radio waves
○ sound waves
○ thermal changes

Explanation:

Medical imaging radiation (like X - rays) causes ionizations in human tissue, which can lead to biochemical changes. Radio waves (non - ionizing, low energy), sound waves (not from radiation), and thermal changes (not the main concern here) don't fit. So the correct option is ionizations.

Answer:

A. ionizations
