Questions With Correct Answers 100%
Verified.
What is energy - Answer✔the ability to do work, that is, to move an object against resistance
what is radiation - Answer✔refers to kinetic energy that passes from one location to another
and can have many manifestations. the transfer of energy
higher frequencies are associated with - Answer✔shorter wavelengths and higher energies
the electromagnetic spectrum can be divided into what two categories - Answer✔-ionizing
radiation
-nonionizing radiation
what part of the electromagnetic spectrum is ionizing radiation - Answer✔-xrays
-gamma rays
-high energy ultraviolet radiation (energy higher than 10 eV)
what part of the electromagnetic spectrum is nonionizing radiation (because they do not have
sufficient kinetic energy to eject electrons from the atom) - Answer✔-low energy ultraviolet
radiation
-visible light
-infrared rays
-microwaves
-radio waves

what is the process of ionization - Answer✔the foundation of the interaction of xrays with
human tissue
it makes the xrays valuable for creating images but has the undesirable result of potentially
producing some damage in human tissue
what is radiation dose - Answer✔the amount of energy transferred to electrons by ionizing
radiation
what is a radiation quantity, equivalent dose (EqD) - Answer✔correlates the absorbed dose in
biologic tissue with the type of energy of the radiation to which human has been subjected,
applies only to ionizing types of radiation
what are the four particulate radiations - Answer✔-alpha particles
-beta particles
-neutrons
-protons
what is particulate radiation - Answer✔subatomic particles that are ejected from atoms at very
high speeds. they possess sufficient kinetic energy to be capable of causing ionization by direct
atomic collision. no ionization occurs when the particles are at rest
alpha particles - Answer✔-emitted from nuclei of very heavy elements during the process of
radioactive decay
-contain 2 protons and 2 neutrons
-have a very large mass
-lose energy quickly as they travel short distances
Beta particles - Answer✔-emitted within the nuclei
-will not interact as strongly with their surroundings
-treat superficial skin lesions
protons - Answer✔-positively charged components of an atom
-small mass
-number of protons is the atomic number z
neutrons - Answer✔-electrically neutral components of an atom
-has the same mass as a proton
