Question

If a substance is emitting radiation very slowly, what can you determine about its half-life.

A. it has a long half-life
B. it has a short half-life
C. it has no half life

Answer 1

B. It has a long half-life

Step-by-step explanation:

A short "half-life" means the substance decays quickly; a long half-life indicates a slower rate of decay. Not all atoms of a particular type of radioactive material will decay at the same time.
