Topic 6 - Radioactivity - Safety Measures

Question 1

What is a key strategy for limiting patient dose in medical procedures?

Answer 1

Use radioactive tracers with a short enough half-life

The half-life should be short enough for the tracer to be removed from the body within a day.

Question 2

What is the ideal half-life duration for common medical tracers?

Answer 2

6 hours

This duration allows the tracers to be detectable while minimizing patient exposure time.

Question 3

What is the importance of the half-life of radioactive tracers?

Answer 3

It must be short enough to be quickly removed but long enough to be detectable

This balance ensures effective medical imaging while protecting patient safety.

Question 4

What safety measure is taken to limit risks to medical personnel during radioactive tests?

Answer 4

Medical personnel leave the room during tests

This practice helps to minimize their long-term exposure to radioactive sources.

Question 5

True or False: Medical personnel can stay in the room during radioactive tests without any safety concerns.

Answer 5

False

Prolonged close proximity to radioactive sources poses health risks.
