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.
What is the most likely potential hazard working with diagnostic radiology?
Carcinogenesis - Stochastic/Non-Threshold Effect
.1 Rem = ? Seivert
1 Sievert
0.1 Gray = ? Rad
10 Rad
,1 Gray = ? Rad
100 Rad
What is Aplastic Anemia? When dose it occur?
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
,Skin Eyrythemia (Skin Redning) occurs above?
Above 200 Rad, 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)
Always practice TDS
Has legal right for re-assignment of duty
Never confuse collar badge with waist badge
Monthly dosimetry reports is based on what?
OCCUPATIONAL exposures only.
Monthly Dosimeter reports does NOT include?
Natural or Background Radiation
, What is the recommended monthly dose-equivalent limit for the fetus in the third trimester?
0.5 mSv
.05 Rem

Age x 1 Rem
NCRP 110
What is the Occupational radiation dose equivalent limit for stochastic effects to the whole body?
50 mSv (5 Rem)
When using a C-Arm mobile unit, the intensification tower should be?
As close as possible to the patient to reduce patient dose and unnecessary magnification.
Radiation exposure in air = ?
Roentgens - Ionization in air dose measurement.
