EXAM PREP 2025 (MOST RECENT!!)
How far away must the operator stand from the xray tube if not
covered with lead? .....ANSWER..... 3 meters
90% of man made radiation to the population is related to?
.....ANSWER..... Medical Radiography and Dental
For each peak xray voltage, what lead equivalent is required?
100kV or less (o-100)
Between 101kV-149kV
150kV or greater (150+) .....ANSWER..... 0-100kV = 0.25mm of
lead
,Page 2 of 48
Greater than 100kV but less then 150kV = 0.35mm of lead
150kV or greater = 0.50mm of lead
What protective equipment is required during interventional
procedures .....ANSWER..... Full wrap around protective gowns of
0.50mm pb in the front panels and 0.25mm pb in the back
panels
Thyroid shields with an equivalent of 0.50mm of pb
Lead drapes/curtains mounted to II of 0.25mm of pb at 100kv
What lead equivalent must protective gloves/ gauntlets possess?
.....ANSWER..... 0.25mm of pb
,Page 3 of 48
What lead equivalent must ceiling mounted lead screens and
moveable shields provide? .....ANSWER..... 0.50mm of pb
What are the annual radiation dose limits for radiation workers?
.....ANSWER..... Whole body= 20mSv
Lens of eye= 150mSv
Skin = 500mSv
Hands = 150mSv
All other organs = 500mSv
For pregnant women an effective dose of 4 mSv must be applied
for the remainder of the pregnancy from all sources
What are the annual radiation dose limits to members of the
public? .....ANSWER..... Whole body = 1mSv
Lens of the eye= 15mSv
, Page 4 of 48
Skin = 50mSv
Hands = 50mSv
All other organs = 50mSv
*these also apply for students*
What are primary protective barriers? Give examples
.....ANSWER..... Primary barriers provide shielding from the direct
xray beam. Such as, the walls and floor where the tube can be
directed
-The wall behind the wall bucky
-Floor under the table
What are secondary barriers and give examples .....ANSWER.....
Provide shielding against both leakage and scattered radiation.
