Most personnel overexposures could be prevented by performing a radiation survey:
A: at the restricted area perimeter
B: before a radiographic exposure
C: before shipping or transporting the exposure device
D: after a radiographic exposure
D
A radiographer discovers the dosimeter being worn is off-scale. Which of the following action is
appropriate?
A: radiographic work should be halted until the dosimeter is recharged
B: Re-zero the dosimeter and notify the RSO prior to resumption of radiographic operations
C: obtain another dosimeter and return to work
D: the radiographer's film badge/TLD should be sent for immediate processing before returning to
work in a radiation area
D
Which of the following describes the relationship between wavelength of X-rays and their
penetrating ability?
A: longer wavelength X-rays are higher energy, and therefore more penetrating
, B: longer wavelength X-rays are more penetrating than shorter wavelength X-rays
C: shorter wavelength X-rays are of lower energy, and therefore less penetrating
D: shorter wavelength X-rays are more penetrating than longer wavelength X-rays
D
As a source is retracted into the shielded position from a collimated exposure, the survey meter
measurement should:
A: initially measure zero, then steadily increase
B: increase, then decrease
C: decrease, then increase
D: increase, then remain constant
B
If a package of radioactive material is transported in an open vehicle, what maximum radiation level
is permitted at the exterior of the vehicle?
A: 2 mR/hr
B: 50 mR/hr
C: 200 mR/hr
D: 1000 mR/hr
C
The term used to express the number of curies of radioactivity per unit of source weight is:
A: decay
B: emissivity
C: specific activity
D: source output
C
X-ray machine control panels must:
A: include a readout from a radiation monitor inside the exposure room that verifies that x-rays are
being produced
B: have a "dead-man" switch that must be constantly depressed for the X-ray machine to produce X-
rays
C: have a series of lights that sequence from green to yellow to red when an exposure is initiated
D: have some positive visual indication that X-rays are being generated
D
A survey meter placed against the surface of an exposure device indicates no radiation level;
however, the survey meter was working properly for several previous exposures. What cause of
action should be taken by the radiographer?
A: cease operations until another calibrated and operational survey meter can be obtained
B: if the exposure equipment is still in working order, complete the next exposure, maintain an
increased level of awareness of the restricted area and use the assistants' audible alarm as a
temporary high radiation area alarm
C: notify the RSO immediately and file a report of the incident
D: proceed with an additional exposure to verify that the survey meter is not operational
