QUESTIONS AND CORRECT ANSWERS
(VERIFIED ANSWERS) |ALREADY GRADED
A+
U.S Nuclear Regulatory Commission (NRC) - CORRECT ANSWER what
agency is responsible for regulation of the purchase, receipt, use, and
disposal of radioactive materials
Agreement State - CORRECT ANSWER a state that accepts
responsibility for the regulation of all radioactive materials
Federal facilities (ex. VA hospitals and military installations) - CORRECT
ANSWER Which facilities in agreement states are still regulated by the
NRC?
A facility license - CORRECT ANSWER How is authorized use of
radioactive material in humans granted by the NRC/state agency
Authorized Users - CORRECT 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) - CORRECT ANSWER what
agency controls the packaging and interstate movement of hazardous
materials including radioactivity
Type A - CORRECT ANSWER type of package adequate for normal
transport
Type B - CORRECT ANSWER type of package that is more accident
resistant and is used for very large quantities of radioactive materials
transport index - CORRECT ANSWER the dose rate measured at 1
meter from the surface of the package and must appear on the label
White I - CORRECT ANSWER no more than 0.5 mR/hr at contact and
no detectable radioactivity at 1 meter
Yellow II - CORRECT ANSWER no more that 50 mR/hr at contact and
no more than 1 mR/hr at 1 meter
Yellow III - CORRECT 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) - CORRECT ANSWER what
agency regulates and monitors the manufacture, distribution, safety,
and effectiveness of radiopharmaceuticals
drugs that have new drug authorization (NDA) - CORRECT ANSWER
what are the only approved radiopharmaceuticals that can be

investigational new drug (IND) - CORRECT 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 - CORRECT ANSWER what must a patient
receive prior to receiving an IND
time, distance, shielding - CORRECT ANSWER factors in reducing
radiation exposure
total dose=(dose rate)(time) - CORRECT ANSWER equation for total
radiation dose for amount of exposure time
inverse square law - CORRECT 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 - CORRECT ANSWER when doubling distance from a
source how much is dose rate reduced
4 times the original - CORRECT 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 - CORRECT ANSWER equation for the inverse square
law
plastic - CORRECT ANSWER shielding that absorbs beta particles
lead sheilding - CORRECT ANSWER what should not be used on beta
particles such as P-32 and Sr-89
it will cause bremsstrahlung radiation - CORRECT ANSWER why
should lead shielding not be used on P-32 or Sr-89
bremsstrahlung - CORRECT ANSWER radiation that results from the
deceleration of the beta particles as they approach the nuclei of the
lead atoms in the sheild
