Radiation is what? ✔Correct Answer-Energy that travels through space as a wave or a stream
of particles.
Wave ✔Correct Answer-An x-ray is an ionizing form of radiation that travels in a...
What is a picture? ✔Correct Answer-A radiograph that is produced when x-rays pass through
an object and then interact with a receptor which is sensitive to radiation.
Radiolucent (black or dark gray) areas: ✔Correct Answer-Show where x-rays passed through
tissue and reached the receptor.
Radiopaque (white or light gray) areas: ✔Correct Answer-Show that x-rays were blocked and
unable to reach the receptor.
Density ✔Correct Answer-Darkness
Contrast ✔Correct Answer-Shading of the radiograph
Wilhelm Conrad Roentgen ✔Correct Answer-Discovered x-rays in 1895
Dr. William Rollins ✔Correct Answer-gave warnings after burns to hand and created the first
collimator.
Dr. C. Edmond Kells ✔Correct Answer-Cancer of the hands and committed suicide
Matter ✔Correct Answer-Anything that occupies space.
What is matter made of? ✔Correct Answer-tiny particles called atoms
Nucleus and 3 particles of the atom ✔Correct Answer-protons, neutrons, and electrons
Protons ✔Correct Answer-positive
Neutrons ✔Correct Answer-neutral
Electrons ✔Correct Answer-negative and orbit around nucleus
, Ionization ✔Correct Answer-Process of losing or gaining electrons producing charged particles
called ions. Makes changes on receptors and tissues.
What happens when x-rays pass through any substance? ✔Correct Answer-Ionization
Dental radiation is: ✔Correct Answer-Ionizing
Natural radiation ✔Correct Answer-Given off when unstable atoms undergo decay.
Radon gas ✔Correct Answer-Given off from the Earth when radium undergoes decay and is a
MAJOR source of radiation to humans
Man-made radiation ✔Correct Answer-Generated by machines such as lasers, x-rays, and
tanning beds
Dental radiation makes up what % of background radiation ✔Correct Answer-0.10%
Radon radiation makes up what % of background radiation ✔Correct Answer-55%
Forms of radiation ✔Correct Answer-Particulate and electromagnetic
Particulate radiation ✔Correct Answer-Tiny particles that move through space very quickly
Electromagnetic radiation ✔Correct Answer-Bundles of energy that travel through space in a
wave.
Electromagnetic radiation waves include: ✔Correct Answer-radio, microwaves, TV waves,
light, sunlight, x-rays, and gamma rays
Gamma rays originate from: ✔Correct Answer-A different part of the atom
X-rays and gamma rays can be stopped by ✔Correct Answer-lead
Electromagnetic spectrum ✔Correct Answer-All electromagnetic energy arranged in order
according to wavelength and strength
Stronger electromagnetic waves are ✔Correct Answer-Ionizing which means they interact and
change things
Are dental x-rays ionizing? ✔Correct Answer-Yes
x-ray machine parts ✔Correct Answer-Tubehead, x-ray tube, beam indicating device (BID),
extension arm, control panel, exposure button, power supply
