d. a ||branch ||of ||medicine ||that ||deals ||with ||the ||use ||of ||x-rays.
ANSWER: | | A
Radiation ||is ||a ||form ||of ||energy ||carried ||by ||waves ||or ||streams ||of ||particles. ||An ||x-ray ||is ||a ||beam
||of|energy ||that ||has ||the ||power ||to ||penetrate ||substances ||and ||record ||image ||shadows ||on ||a
||receptor.
X-radiation ||is ||a ||high-energy ||radiation ||produced ||by ||the ||collision ||of ||a ||beam ||of ||electrons ||with
||a|metal ||target ||in ||an ||x-ray ||tube. ||Radiology ||is ||a ||branch ||of ||medicine ||that ||deals ||with ||the ||use ||of
