CORRECT VERIFIED ANSWERS/ ALREADY GRADED A+
(BRAND NEW!!)
Energy .....ANSWER..... Radiation that travels through space as a
wave or a stream of particles.
X-ray .....ANSWER..... An ionizing form of radiation that travels in
a wave.
Radiograph .....ANSWER..... A picture produced when x-rays
pass through an object and then interact with a receptor which is
sensitive to radiation.
Radiolucent Areas .....ANSWER..... Show where x-rays passed
through tissue and reached the receptor. Dark gray and black
,Page 2 of 46
Radiopaque Areas .....ANSWER..... Show that x-rays were
blocked and unable to reach the receptor. They are white or
light gray
Density .....ANSWER..... In a radiograph, this refers to the
darkness
Contrast .....ANSWER..... In a radiograph, this refers to the
shading
Wilhelm Conrad Roentgen .....ANSWER..... Who discovered x-
rays in 1895?
Dr. William Rollins .....ANSWER..... He gave warnings after a
burn to the hand and created the first collimator.
Dr. C. Edmond Kells .....ANSWER..... He developed cancer of the
hands and committed suicide because of radiation related pain.
Atoms .....ANSWER..... Is the smallest unit of matter
Matter .....ANSWER..... Anything that occupies space is what?
,Page 3 of 46
Nucleus .....ANSWER..... What else do atoms have besides three
particles?
Proton, neutron, and electron .....ANSWER..... What are the 3
particles of an atom called?
Proton .....ANSWER..... Which particle is positive?
Neutron .....ANSWER..... Which particle is neutral?
Electron .....ANSWER..... Which particle is negative and orbits the
nucleus?
Ions .....ANSWER..... Ionization is the process of losing or gaining
electrons that produce particles called what?
Ionization .....ANSWER..... This is what happens when x-rays pass
through any substance. It can make changes to your tissue
Ionizing .....ANSWER..... Dental radiation can pass through tissue
so it is?
, Page 4 of 46
Man-made and natural .....ANSWER..... What are the types of
radiation?
Natural .....ANSWER..... This type of radiation is given off when
unstable atoms undergo decay. Ex, space, sun, elements
Man-made .....ANSWER..... This type of radiation is generated by
machines such as lasers, x-rays, and tanning beds.
Radon Gas .....ANSWER..... This is given off from the earth when
radium undergoes decay is a major source of exposure to
humans. 55 % of background radiation
Background radiation .....ANSWER..... This is radiation existing in
the environment from both sources.
Dental Radiation .....ANSWER..... This accounts for 0.10% of
background radiation.
Particulate and electromagnetic .....ANSWER..... These are the
forms of radiation.
