How far away must the operator stand from the xray tube if not covered with
lead? - - CORRECT ANSWER - >3 meters

90% of man made radiation to the population is related to? - - CORRECT 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+) - - CORRECT 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 - -
CORRECT 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

- CORRECT ANSWER - >0.25mm of pb

What lead equivalent must ceiling mounted lead screens and moveable shields
provide? - - CORRECT ANSWER - >0.50mm of pb

What are the annual radiation dose limits for radiation workers? -
- CORRECT 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? -
- CORRECT 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 - - CORRECT ANSWER -
>Primary barriers provide shielding from the direct xray beam. Such as, the walls
and floor where the tube can be directed

-Floor under the table

What are secondary barriers and give examples - - CORRECT 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.

What should the focal spot to skin distance be for:

-Mobile equipment
-Stationary equipment
-Radioscopic equipment - - CORRECT ANSWER - >Must not be less than:

-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 - - CORRECT ANSWER - >Not equipped with AIC: 50mGy/min

With AIC: 100mGy/min

The air kerma rate must not exceed ___ from scattered radiation of radioscopic
equipment - - CORRECT ANSWER - >2 mGy/h
