ARRT Test Prep, LIMITED X-RAY
CORE questions and answers 2024\2025
Grade A+
Main property of x-radiation that makes it potentially hazardous is its ability to?
- correct answer Ionize
Describe the damage potential of ionization?

A decrease in blood count is the earliest response seen to dose radiation. It can occur at dosease as low
as?
- correct answer 25 Rads or .25 Gray
What is Cataractogenesis?
- correct answer Process of Cataract Formation
Cataractogenesis occurs after acute or chronic exposures of how many Rads?
- correct answer 200 Rads, 2 Gray

- correct answer Above 200 Rad, 2 Gray
Temporary Sterility occurs in the adult male at acute doses of how many Rads?
- correct answer 250 Rads, 2.5 Gray
Pregnant radiographer should? (3)
- correct answer Always practice TDS
Has legal right for re-assignment of duty

When using a C-Arm mobile unit, the intensification tower should be?
- correct answer As close as possible to the patient to reduce patient dose and unnecessary
magnification.
Radiation exposure in air = ?
- correct answer Roentgens - Ionization in air dose measurement.
Electrical current being generated by a charge created in air thru ionization by x/gamma radiation is
called a?

The quantity of radiation exposure measured by an ionization chamber would be?
- correct answer Coulomb/Kilogram
The C/Kg or R is usually the unit measured in?
- correct answer Air dose
List the 3 measurements that are more appropriate for measuring absorbed doses for radiation or
occupational dose?
- correct answer Gray (1) - Rad (100)
, Seivert (1) - Rem (100)
Curie - Bacquerel
What type of changes are used to measure occupational dose? (3)

emulsion--a definite chemical change.
How long can a film badge be worn?
- correct answer No more than a month
Why shouldn't film badges be worn greater than a month?
- correct answer Extreme sensitivity to environmental conditions.
TLD's operate thru?
