Radiation Protection - Chapter 4 Exam
Questions With Correct Answers 100%
Verified.
Linear Energy Transfer (LET) - Answer✔The amount of energy deposited by radiation per unit
length of tissue; amount transferred to an object per unit length of track, or passage, through
the object
Sv - Answer✔SI unit of EqD.
Occupational Exposure - Answer✔Radiation exposure received by radiation workers in the
course of exercising their professional responsibilites.
Absorbed Dose (D) - Answer✔The amount of energy per unit mass absorbed by an irradiated
object.
Air Kerma - Answer✔SI quantity that can be used to express radiation energy transferred to a
point, such as the surface of a patient's or radiographer's body; kinetic energy released in a unit
mass (kilogram) of air
Collective Effective Dose (ColEfD) - Answer✔Designed for use in the description of a population
or group exposed to different individual amounts of ionizing radiation. It is equal to the sum of
all of the doses times the number of individuals exposed and would be expressed in units such
as person-Sv.
Committed Effective Dose Equivalent (CEDE) - Answer✔A measure of the probablistic health
effect on an individual as a result of intake of radioactive material into the body. It takes into
account the length of time that the radioactive material may stay within the body.
Coulomb (C) - Answer✔Basic SI unit of electrical charge. It represents the quantity of electrical
charge flowing past a point in a circuit in 1 second when an electrical current of 1 ampere is
used.
Coulombs per kilogram (C/kg) - Answer✔SI unit of radiation exposure.
