the main ingredient.
Are medicinal products designed for the use in the
investigation or treatment of human diseases

Answer 16

Radiopharmaceuticals

Question 17

The atoms involved and the only nuclei
that undergo radioactive decay
▪ Emits gamma ray as it decays
▪ This is tagged to a radiopharmaceutical

Answer 17

Radionuclide

Question 18

Any chemical substances intended for use in medical
diagnosis, cure treatment or prevention of disease.
▪ Carries the radionuclide to the organ being
examined.
▪ This is chosen in the basis of its preferential
localization or participation in the physiological
function of a given organ.
▪ Produces gamma-ray emission from within the
organ is being studied.

Answer 18

Pharmaceuticals/Tracer
