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
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
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
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. Walls that the primary beam is not
directed towards and the ceiling are secondary barriers.
The control booth is also a secondary barrier, the primary beam should never be
directed towards it.

-Mobile: 30cm
-Stationary: 38cm
-Radioscopic: 20cm (designed for special procedures that would be impossible at
30cm or 38cm)
What are the maximum air kerma rates for radioscopic equipment:
-with automatic intensity control
-without AIC - ANSWER Not equipped with AIC: 50mGy/min
With AIC: 100mGy/min
The air kerma rate must not exceed ___ from scattered radiation of radioscopic
equipment - ANSWER 2 mGy/h
HVL of Aluminum for given tube voltages? (70kV-150kV) - ANSWER 70: 2.5mm
