Nuclear Medicine/Pharmacy Quiz

In nuclear medicine/pharmacy, what does the word "dose" refer to?

• The measurement of how much radiation is deposited in a person

• The amount of medication given to a patient

• The time taken for a medication to take effect

• The cost of a medical procedure

What does "radiation dose" refer to in the context of nuclear medicine/pharmacy?

• Physical impact on the body

• Amount of medication given

• Frequency of treatment

• Cost of treatment

What can the intervening medium do to ionizing radiation?

• Absorb and scatter radiation

• Increase and decrease radiation

• Speed up and slow down radiation

• Change the color of radiation

What does the number of atoms that decay per second indicate?

• Energy deposition

• Activity

• Radiation level

• Disintegration rate

What is the primary concern when first learning how to handle radioactivity?

• Internal exposure

• External exposure

• Both internal and external exposure

• Neither internal nor external exposure

What is the main difference between internal and external exposure?

• Internal exposure is from ingestion, external is from proximity

• Internal exposure is from proximity, external is from ingestion

• Internal exposure is from medical imaging, external is from waste handling

• Internal exposure is from waste handling, external is from medical imaging

What does the unit Roentgen (R) fail to represent accurately?

• 1 cm

• 1 m

• 10 cm

• 10 m

Are the values of the Specific Gamma Ray Constant (Γ) the same for all isotopes?

• No, they are specific for each isotope

• Yes, they are the same for all isotopes

• They vary only slightly

• They are the same for isotopes of the same element
