Dental Assisting Iowa RDA Radiology Test
1. What two agencies oversee dental radiography? what is
the function of each with respect to dental radiography?
Ans: Iowa Department of Public Health: state radiation control
agency, inspects facilities
Iowa Dental Board: ensures that dental assistants meet minimum
training standards, issues qualification in dental radiology
2. Under what conditions can a dental assistant take
radiographs?
Ans:
1- assistant must have added qualified in dental radiography or
be on trainee status
2- dentist must order the films
3- dentist must provide supervision
3. Under what conditions can a dental assistant trainee
take radiographs?
Ans:
1-dentist must order films
2- dentist must provide personal supervision of trainee
4. What three things are required to obtain radiography
qualification from the Board?
,Ans: Course of study that includes clinical training, examination,
and an application with fee
5. When is the radiography qualification renewed? What
are the renewal requirements?
Ans: Renewed when registration is renewed- by August 31 of odd
years
6. What are the renewal requirements for dental
radiography?

12. what are the parts of the control panel and what do
they do?
Ans: 1- timer controls how long electrons move- length of
exposure
2-mA setting- determines the number of electrons available
3- kVp setting- determines the force of electron movement
13. A source of electrons is needed to create x-rays. What
else is needed to create x-rays?
Ans: motion to the electrons something to stop the electrons
14. What determines the number of electrons that will be
used?
Ans: mA and time
15. what role does kinetic energy play in the creation of x-
rays?
Ans: Electrons in motion possess kinetic energy; kinetic energy
from electrons in motion is converted into heat and x-rays when
the electrons are stopped.
