These atoms are smaller and do not absorb x-rays as well as the heavy atoms that make up bones, such as calcium.
What are soft body tissue atoms
100
X-rays are a form of energy that exhibits wavelike behavior as it travels through space (carried by photon particles), otherwise known as this.
What is electromagnetic radiation
100
Electrons from a cathode hit the atoms and nuclei of a target metal, such as this, due to a high voltage.
What is tungsten
100
In absorption, an atom absorbs this which causes an electron to become excited and move to a higher energy level.
What is a photon
100
In emission, this action causes an electron to emit energy in the from of a photon.
What is dropping to a lower energy level
200
Photographic films use ____ to show x-rays interacting with the body. Areas exposed to more light are darker than areas exposed to less light.
What are negative images
200
X-rays can pass through things that light cannot because their photons have this.
What is higher energies
200
This method of creating x-rays occurs when the electron comes near the nucleus of the target metal but slows down and deviates from its course due to electromagnetic interaction. This kinetic energy becomes an x-ray.
What is Bremsstrahlung
200
This is when the intensity of radiation decreases as it passes through a material.
What is attenuation
200
In k-shell emission, the ____ of the photon (or x-ray) emitted is the same as the energy difference between the orbitals.
What is energy
300
X-rays are commonly used to detect the development in these in dentistry
What are wisdom teeth
300
X-rays were discovered by German physicist Wilhelm Roentgen in this year.
What is 1895
300
These kind of metals work best when creating x-rays since they produce a more intense ray. For example, tungsten can withstand electron collisions because of its high melting point and ability to conduct heat well.
What are heavy metals
300
Attenuation is due to Compton scattering or this type of absorption
What is photoelectric absorption
300
This kind of x-ray emission creates more intense rays than Bremsstrahlung.
What is k-shell emission.
400
X-rays can be used in ____ to detect flaws without causing damage
What is heavy metal equipment
400
While experimenting with this tube, Roentgen noticed that a fluorescent screen at the end of the table would glow when the tube sparked due to strange rays.
What is a cathode ray discharge tube.
400
This x-ray production method occurs when an approaching electron excites one of the metal's electrons, causing a vacancy in the orbital which has to be filled by an electron in a higher orbital (which releases energy in the form of a photon or x-ray).
What is k-shell emission
400
Thick and dense materials such as bones and fillings absorb more x-rays, which is why they appear this color on photographic plates.
What is white
400
Various objects in the solar system emit x-rays, such as the most famous star in the Milky Way galaxy.
What is the sun
500
This medical technique is produced when a narrow beam of x-rays are shot through the body from many different angles
What is a CAT scan
500
The wavelength of an x-ray ranges from 0.1 to 100 of this unit.
What is angstroms
500
K-shell emission forms this type of x-ray.
What is a characteristic x-ray
500
Patients often wear aprons made of this metal because it absorbs the x-rays so they do not pass to other parts of the body.
What is lead
500
This was the first cosmic x-ray source discovered.
