Question Number: 941 Applied Radiation Protection
The term "Reference Man" in health physics is:
A) the mathematically correct human being with organs which are defined by
spheroids and ellipsoids to make a technically correct body for dosimetry evaluations.
B) the phantom which is used to reference a body counter to a standard.
C) a set of agreed upon values for the many characteristics of the human body which
are needed for internal dose evaluations.
D) a man of large stature to ensure conservative interpretation of dose to any
individual.
,E) a set of agreed upon values for exposure times and rates that the normal human
could tolerate.

The correct answer is: C
The anatomical characteristics of Reference Man are listed in ICRP
Publication 23 and in ICRP 89.
Question Number: 714 Applied Radiation Protection
General area dose rates should be recorded:
A) as the dose rate at the chest.
B) as the dose rate at the waist.
C) as the dose rate at the knees.
D) as the highest dose rate between the head and knees.
E) as the highest dose rate between the chest and knees.

The correct answer is: D
"General area dose rates" are usually taken to determine deep dose
equivalent rates in a work area, and don't include shallow dose equivalent
rates to extremities (arms below the elbow, legs below the knee).
Question Number: 746 Applied Radiation Protection
A compound which is effective to remove radioactive contamination from the skin,
after soap and lukewarm water have been ineffective is which of the following?
,A) Acetone
B) Diethylene-triamine-pentaacetate (DTPA)
C) Trinitro toluene (TNT)
D) Potassium permanganate (KMnO4)
E) Nitrile triacetic acid

The correct answer is: D
KMnO4 will remove the first few layers of skin, and should only be used
under medical supervision. Titanium dioxide paste has the same
application. DTPA is an internal chelating agent for plutonium and
americium. A risk analysis should be performed relative to the radioactivity
to be removed whenever using these types of materials.
Question Number: 960 Applied Radiation Protection
Klystron tubes used to generate RF accelerating fields for accelerators:
A) are not a major radiological concern, but a magnatron would be a concern.
B) are strictly an RF hazard, and as such, should always be checked to verify that the
SAR limits are not exceeded.
C) should be checked for x-ray production and leakage, especially in the region
around the RF output waveguides and beam collimator cooling connections.
D) produce x-rays in predictable, reliable patterns, such that an initial installation
survey is necessary, and subsequent surveys are only required when the unit is either
moved or upgraded.
E) generate x-rays when a vacuum is present, and the number of x-rays will gradually
go down as vacuum is lost.

, The correct answer is: C
The converse of answers A and E are true. NCRP Report 144, pg. 25-26.
Question Number: 817 Applied Radiation Protection
When is a neutron radiation survey usually performed?
A) After reactor startup
B) Upon receipt of a radioactive materials shipment
C) When there are suspected fuel cladding failures within the active fuel inside the
reactor
D) Before an object is released from a controlled area
E) None of the above
Give this one a try later!
The correct answer is: A
As the reactor goes through its power ascension, neutron dose rates in
surrounding areas will increase. If control rods are in a different
configuration than during the previous reactor run, the location of the
neutron fields will most likely be different.
Question Number: 938 Applied Radiation Protection
Reference Man's air inhalation under conditions of light activity for an eight-hour
period is approximately:
A) 1 x 106 cc
B) 1 x 107 cc
C) 3 x 107 cc
