Main property of x-radiation that makes it potentially hazardous is its
ability to?
Ionize
Describe the damage potential of ionization?
Chain reaction in the human body that may eventually cause biologic
damage. X-rays are from the Electric Magnetic Spectrum or radiation
energy and is considered harmful in high energy ranges.

radiology?
Carcinogenesis - Stochastic/Non-Threshold Effect
.1 Rem = ? Seivert
1 Sievert
0.1 Gray = ? Rad
10 Rad
1 Gray = ? Rad
100 Rad

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

Temporary Sterility occurs in the adult male at acute doses of how many
Rads?
250 Rads, 2.5 Gray
Pregnant radiographer should? (3)

Biological
Chemical
Underexposed radiograph produced by AEC device might result from?
Having insufficient backup time set for a very large patient
Appearance of grid lines on radiograph with the table Bucky in use
indicates?
Exposure time too short
What would be used by tech to compensate for the caring densities of
anatomic structures on a routine PA projection of the chest?
Trough Filter
