Guaranteed Pass
U.S Nuclear Regulatory Commission (NRC) - Answer✔what agency is responsible for regulation
of the purchase, receipt, use, and disposal of radioactive materials
Agreement State - Answer✔a state that accepts responsibility for the regulation of all
radioactive materials
Federal facilities (ex. VA hospitals and military installations) - Answer✔Which facilities in
agreement states are still regulated by the NRC?
A facility license - Answer✔How is authorized use of radioactive material in humans granted by
the NRC/state agency
Authorized Users - Answer✔who are responsible for supervising individuals working with
radioactive material, determining radiation safety procedures and establishing dosage activity
ranges
U.S. Department of Transportation (DOT) - Answer✔what agency controls the packaging and
interstate movement of hazardous materials including radioactivity
Type A - Answer✔type of package adequate for normal transport

Type B - Answer✔type of package that is more accident resistant and is used for very large
quantities of radioactive materials
transport index - Answer✔the dose rate measured at 1 meter from the surface of the package
and must appear on the label
White I - Answer✔no more than 0.5 mR/hr at contact and no detectable radioactivity at 1
meter
Yellow II - Answer✔no more that 50 mR/hr at contact and no more than 1 mR/hr at 1 meter
Yellow III - Answer✔no more than 200 mR/hr at contact and no more than 10 mR/hr at 1 meter
U.S. Food and Drug Administration (FDA) - Answer✔what agency regulates and monitors the
manufacture, distribution, safety, and effectiveness of radiopharmaceuticals
drugs that have new drug authorization (NDA) - Answer✔what are the only approved
radiopharmaceuticals that can be distributed for sale in the US
investigational new drug (IND) - Answer✔a drug that is under investigation by the FDA and may
only be used on patients under very controlled conditions
an informed written consent - Answer✔what must a patient receive prior to receiving an IND
time, distance, shielding - Answer✔factors in reducing radiation exposure
total dose=(dose rate)(time) - Answer✔equation for total radiation dose for amount of
exposure time
2

inverse square law - Answer✔the radiation dose rate from a small-volume radiation source
varies inversely with the square of the distance from the source is known as
1/4 the original - Answer✔when doubling distance from a source how much is dose rate
reduced
4 times the original - Answer✔when distance from source is halved how much is the dose rate
increased
(I1)(D1)^2=(I2)(D2)^2
I1=dose rate at distance D1 from source and I2 is dose rate at distance D2 from source -
Answer✔equation for the inverse square law
plastic - Answer✔shielding that absorbs beta particles
lead sheilding - Answer✔what should not be used on beta particles such as P-32 and Sr-89
it will cause bremsstrahlung radiation - Answer✔why should lead shielding not be used on P-32
or Sr-89
bremsstrahlung - Answer✔radiation that results from the deceleration of the beta particles as
they approach the nuclei of the lead atoms in the sheild
lose energy and and are released as xrays - Answer✔what happens when beta particles slow
down
lead, leaded glass, and tungsten - Answer✔shielding used to reduce x and gamma rays
3

half-value layer (HVL) - Answer✔the ability of a material to absorb/attenuate x and gamma rays
and the thickness of material that id required to reduce radiation intensity to half its original
film badges, thermoluminescent dosimeter, optically stimulated luminescence dosimeter,
pocket ionization chambers - Answer✔types of dosimeters
film badges - Answer✔dosimeter that has strip of film between a set of filters that can assess
the energy range and penetration of radiation and can also be exposed to beta particles and
low energy photons. can measure 0.1 mSv-several SV of radiation. Should be changed monthly.
thermoluminescent - Answer✔dosimeter that uses lithium fluoride crystals that emits a
quantity of light proportional to the amount of radiation absorbed, more expensive but not
effected by head or environmental changes, changed 2-3 months
optically stimulated luminescence doismeter - Answer✔dosimeter that uses thin slice of
aluminum oxide to detect radiation exposure and a laser is used to read the badge. heat,
moisture, and aging resistant. more sensitive and changed every 3 months
pocket ionization chamber - Answer✔dosimeter that gives immediate radiation exposure
measurements, more expensive and require careful handling
total effective dose equivalent (TEDE) - Answer✔the sum of the deep dose equivalent and the
committed effective dose equivalent and is known as general exposure measurement
deep dose equivalent (DDE) - Answer✔exposure to the internal organs from external sources is
known as
committed effective dose equivalent (CEDE) - Answer✔exposure to internal organs from
internal sources is known as
