Question

((Bruv pls hurry on test)) Radioisotopes often emit alpha particles, beta particles, or gamma rays. The distance they travel through matter increases in order from alpha to gamma. Each radioisotope has a characteristic half-life, which is the time needed for half of a sample of radioisotope to undergo nuclear decay.

Which quality is desirable for a radioisotope that is used for medical imaging of a specific organ? Check all that apply.

half-life of several years
half-life of several days
half-life of several seconds
emission of gamma rays
emission of alpha particles
ability to be attached to a compound used by the body
ability to pass through the body without being absorbed

Answer 1

2. half-life of several days

4. emission of gamma rays

6. ability to be attached to a compound used by the body
