Answer 1

a-It takes 10 to 12 eV or more to break the bond of molecular elements. Radiant sources below this level are considered ___visible sources___. Sources above this level are considered ____uv sources___. Circle the one that is generally considered more dangerous. : uv sourcs

b- When microwave radiation is absorbed in the human body:

a. It passes through harmlessly b. It liberates electrons from atoms c. It is primarily converted to heat d. It creates cations and anions

ans: (c) as, microwaves cause internal heating of body tissues. infrared radiation is felt as heatand causes skin burns. X-rays damage cells, causing mutations (which may leadto cancer) and cell death. gamma rays also damage cells, causing mutations(which may lead to cancer) and cell death.
