IRRSP FINAL PAPER QUESTIONS AND
SOLUTIONS
◉ high-speed electrons are emitted from the cathode and strike
the target within a vacuum-sealed envelope.
Answer: X-radiation is produced when a supply of:
◉ free electrons, means of acceleration, and a target.
Answer: Three things needed to generate an x-ray are:
◉ copper and tungsten.
Answer: The two most common materials used for the anode are:
◉ heat.
Answer: Most of the energy used in producing x-rays converts to:
◉ penetrating ability of the radiation.
Answer: The kilovoltage of an x-ray machine is mainly adjusted to
change the:
◉ directly proportional to the quantity of x-rays produced.
Answer: The milliamperage of an x-ray machine is:
,◉ voltage, amperage, and time.
Answer: Three items that can be adjusted on an x-ray machine
are:
◉ bremsstrahlung.
Answer: The process of an electron slowing down as it travels
around the nucleus of an atom and creating an x-ray is called:
◉ characteristic x-rays.
Answer: The process of an inner orbital electron being ejected
from a target atom and having the vacancy filled by an outer
orbital electron which creates an x-ray is called:
◉ polychromatic radiation.
Answer: X-rays emitted from an x-ray machine are referred to as:
◉ beryllium.
Answer: Most x-ray tubes are fitted with a window made of:
◉ duty cycle.
Answer: The time-on to time-off that is needed for an x-ray
machine to cool down is called the:
◉ Survey the part because it could be radioactive.
, Answer: What additional precautions are taken when performing
radiography above 10MeV?
◉ on the electrostatic principle.
Answer: Van de Graaff x-ray machines operate:
◉ in a 360° direction.
Answer: A rod anode x-ray machine will emit x-rays:
◉ greater from a 360° emitter than a directional x-ray tube.
Answer: Scatter radiation from the different x-ray tubes will be:
◉ Caution - x-rays produced when energized.
Answer: The following wording (or something similar) shall be
labeled on an x-ray machine:
◉ Never.
Answer: When can the key used to operate an x-ray machine be
left with the machine while it is unattended?
◉ the radiation safety officer.
Answer: For a safety device or interlock to be bypassed,
permission must be obtained from:
