1. Radiation |is |defined |as
a. a |form |of |energy |carried |by |waves |or |streams |of |particles.
b. a |beam |of |energy |that |has |the |power |to |penetrate |substances |and |record |image
shadows |on |a |receptor.
|
c. a |high-energy |radiation |produced |by |the |collision |of |a |beam |of |electrons |with |a
metal |target |in |an |x-ray |tube.
|
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
x-rays.
