Worked practice questions

A compound is tagged with a radioactive atom and given to a patient so it can be tracked. Such a compound is a:

  1. Radiopharmaceutical
  2. Radiotelescope unit
  3. Radiator component
  4. Radial instrument
Show answer and solution

Correct answer: A. Radiopharmaceutical

1. The compound behaves chemically as the body expects. 2. The tag lets a detector follow where the body sends it. 3. A tagged compound used this way is a radiopharmaceutical. _Source: OpenStax College Physics 2e, Chapter 32, Medical Applications of Nuclear Physics._

The workhorse isotope that can be attached to many compounds to image the skeleton, heart, lungs and kidneys is:

  1. Uranium isotope
  2. Technetium-99m
  3. Carbon isotope
  4. Radon isotope
Show answer and solution

Correct answer: B. Technetium-99m

1. It has to bind to many different carrier molecules. 2. It also has to clear the body quickly so the dose stays small. 3. The isotope that does both jobs is technetium-99m. _Source: OpenStax College Physics 2e, Chapter 32, Medical Applications of Nuclear Physics._

An early imaging device that maps where nuclear activity has concentrated in the body is the Anger camera, also called the:

  1. Gauge camera
  2. Gamma camera
  3. Gravity camera
  4. Grating camera
Show answer and solution

Correct answer: B. Gamma camera

1. The isotope emits gamma rays as it decays. 2. The camera collects those rays to build the picture. 3. It is the gamma camera. _Source: OpenStax College Physics 2e, Chapter 32, Medical Applications of Nuclear Physics._
