Dental Radiation and Safety Exam Study
Guide
The inventor of X-rays in 1895 was
Roentgen
The central beam that comes from the X-ray tube head is ——- radiation
Primary
The radiation formed when the primary X-rays strike the patient is ——- radiation
Secondary
The radiation that is deflected from its path as it strikes matter is ——- radiation
Scatter
The form of radiation that escapes in all directions from the tube head is ——-
radiation
Leakage
,Dental Radiation and Safety Exam Study Guide
The tissues/organs most sensitive to radiation include
Bone marrow and reproductive cells
The effects of radiation are
Cumulative
A dosimeter badge should be worn:
To measure the amount of radiation received for a given period of time
What determines the amount or quantity of radiation?
Milliamperage
What determines the quality of radiation
Kilovoltage
The lead diaphragm determines the size and shape of the
X-ray beam
, Dental Radiation and Safety Exam Study Guide
The size of the most commonly used intraoral film
Size 2
The lead apron with the thyroid collar should be used for
Children, adults, and pregnant women (all of the above)
I'm the paralleling technique, the central beam must be
Perpendicular to the tooth and perpendicular to the film packet
The technique error caused by not having enough angulation is
Elongation
The technique error caused by having too much angulation is
Foreshortening
Incorrect horizontal angulation results in
Overlapping
