Fluoro Practice Exam Questions With Complete Solutions
In digital imaging, adjusting the window level changes the:
Contrast
Adjusting the window level in digital imaging changes the
contrast. Brighter images can be viewed by increasing the
window level and darker images can be viewed by decreasing
the window level.

Residents: Digital Fluoroscopy. Radiographics. 2001;21:521-

Fluoroscopic television systems are:
Closed-circuit
Fluoroscopic television circuits operate between the fluoroscope
and a monitor and are connected with a cable, making them
closed-circuit. Syllabus pg 25.
What is the typical milliampere (mA) usage during spot filming?
a) 0.5-1
b) 1-5
c) 10-50
d) Over 100
Spot films are images taken during an examination using much
higher mA setting, typically over 100.
,Syllabus pg 33.
Exposure to an operator who is wearing a lead apron and facing
the patient occurs primarily where?
(select all that apply)
b) Skull (chosen)
c) Arms (chosen)
d) Clavicles
Operator bone marrow exposure when wearing lead and facing
the patient occurrs primarily in the skull, arms and clavicles.
Syllabus pg 70.
***Somatic dose measurements are taken at what anatomic
sites?
(select all that apply)
a) Gonads
b) Muscle
c) Thyroid (chosen)
d) Skin
e) Bone marrow (chosen)
Somatic refers to the cells of the body that make up the living
tissue with the exception of germ cells. The total somatic effect
includes the entire body, but somatic dose indicators are based
on measurements at specific locations, typically bone marrow,
skin, and thyroid. It is important to understand that the
,measurement of a dose at a single anatomical point cannot
express the total somatic effect. Syllabus pg 59.
All of the following have been used for somatic dose
measurements EXCEPT:
a) Gonads
b) Bone marrow
c) Thyroid
d) Skin
Bone marrow, skin and thyroid are anatomical points that have
been used for somatic dose measurements. Bone marrow dose
is a reasonable indicator of doses to other cancer sensitive
internal organs and is a reasonable indicator
of somatic effects.
Syllabus pg 59-60. Syllabus pg 116 lists organ doses for some
radiology procedures.
In California, how long do an individual's
radiation monitoring records need to be preserved by the
employer?
Indefinitely
Records of dose equivalents received by individuals must be
kept indefinitely.
Syllabus pg 52.
Genetically Significant Dose (GSD) includes the dose the
population receives from background radiation.
, b) FALSE
Genetically significant dose (GSD) was developed to estimate
the magnitude of genetic effects caused by exposure of the
population to radiation. GSD does not include the dose the
population receives from background radiation. Syllabus pg 61.

Immediate notification to the Radiologic Health Branch is
required if an individual receives:
a) A total effective dose equivalent of 0.25 Sv or more -
> Immediate notification is required if an individual has
received 0.25 Sv (total effective dose), 2.5 Sv (shallow
dose equivalent), or 0.75 Sv (eye dose equivalent). Syllabus
