Question 14

Which of the following statements is correct regarding placement of a gonad shield on a female patient?
A) Required on patients over the age of 55
B) Placed with its lower margin at the level of the pubic symphysis
C) Positioned with its upper margin about 1 inch below the pubic symphysis
D) Only used when gonads are within the primary radiation field
E) Both A and B

Accepted Answer

The female shield is placed with its lower margin at the level of the pubic symphysis. The male shield is positioned with its upper margin about 1 inch below the pubic symphysis. Lead shields that prevent unnecessary radiation exposure to the reproductive organs are required when the patient is of reproductive age or younger; whenever the gonads are within the primary radiation field; and when the shield will not interfere with the examination. This applies to most patients under age 55.
