Question Number: 699 Applied Radiation Protection
For calculating dose to an organ from internal sources, the
"specific effective energy" of a radionuclide is BEST described
as:
A) the energy given off by the radionuclide per unit of
radionuclide activity.
B) the energy absorbed per unit mass of the organ per unit of
radionuclide activity.
C) the energy absorbed per unit mass of the organ per
disintegration of the radionuclide.
D) the energy given off by the radionuclide per disintegration
of the radionuclide.
E) the energy transferred to the organ per unit of radionuclide
activity. - Correct Answers ✅The correct answer is: C
The "SEE" is used in the Medical Internal Radiation Dosimetry
(MIRD) dose modeling technique.

A) Wait 3.25 days and prepare for shipment to a disposal
facility or incinerate.
B) Wait 1.625 days and bury.
C) Wait 3.25 days and bury.
D) Wait 32.5 days and prepare for shipment to a disposal
facility or incinerate.

correct answer is: D
It is common for radioactive materials licenses to allow the
disposal of radioactive materials after ten half-lives as "clean"
materials. In this case, the waste is still biohazardous, so
proper burial or incineration is indicated.
Question Number: 701 Applied Radiation Protection
The major radiological health concern associated with burial
of low level solid radioactive waste is:
A) external radiation at the surface of the burial site.
B) contamination of potable water supplies.
C) airborne radioactivity resulting from contaminated soil.
D) release of volatile radioactive daughter products.

E) contamination of vegetables grown in soil at the site. -
Correct Answers ✅The correct answer is: B
The critical exposure pathway for near-surface disposal of
radioactive materials is through drinking water. Most of the
regulations surrounding the burial of radioactive materials,
such as waste classification and stabilization requirements,
are designed to prevent contamination of potable (drinkable)
water.
Question Number: 702 Applied Radiation Protection
An adequate Radiation Safety Program is the ultimate
responsibility of:
A) the owner of the licensed facility.
B) the operator of the source of radiation.
C) the Radiation Safety Officer.
D) the line supervisor.
E) the radiation worker. - Correct Answers ✅The correct
answer is: A
The radioactive materials license is issued to the owner of the
facility. It is the licensee who is responsible for all aspects of
compliance with the license, including the implementation of

a radiation safety program. It is the duty of the RSO to
administer the program.
Question Number: 703 Applied Radiation Protection
An x-ray machine is operated in a closed room for several
minutes. After the machine is turned off, how long should the
operator wait before entering the room?
A) He may enter immediately.
B) 10 seconds
C) 30 seconds
D) 1 minute
E) 1 hour - Correct Answers ✅The correct answer is: A
When the current to the x-ray tube is turned off, the
production of electrons stops. The principle behind x-ray
production in the tube is bremsstrahlung of these electrons
with the target material. When the electron production stops,
so does the x-ray production. There is, of course, no
radioactive material in an x-ray machine.
