1

in what year does roentgen discover x-ray? (( was on the quiz ))

11/8/1895 Wilhelm Conrad Roentgen discovered X-ray accidentally while working in his lab. It was then called x-ray or Roentgen ray.

2

(( was on the quiz)) true or false x way was by other scientist and they were able to grasp it significance ?

False. X-ray was discovered before Roentgen by other scientist, however, all failed to grasp its significance.

3

what was the name of title on the first report of X-ray? (( was on the quiz ))

7

Radiology defined as (( was on the quiz ))

The branch of health sciences dealing with radioactive substances and radiant energy and with the diagnosis and treatment of disease by means of both ionizing and non-ionizing radiation.

8

what is the definition of Radiation ? (( was on the quiz))

Energy transmitted by waves through space or matter. It can also be said to be a form of energy that can be transmitted through matter.

9

what is energy?

The capacity to do work. Higher forms of energy (radiation) can ionize atoms in nature.

10

what is Ionization? ( (was on quiz))

Process by which a neutral atom gains or looses electrons. This process has the ability to disrupt the composition of matter, thus disrupting the life process. Therefore, exposure to radiation is limited.

11

what is an X-ray?

Man-made form of electromagnetic energy. X-rays are created when electrons moving at high speed are suddenly stopped.

12

a Radiologist defined as ?

The physician who specializes in the use of roentgen rays and other forms of energy in the diagnosis and treatment of disease.

what do Radiologic Technologist do ?

The individual who performs radiography or medical imaging of the internal

15
