What property of half-lives makes radioactive material so problematic?
A)There is no known way to shorten a half-life.
B)Radioactivity is limited by the natural decay-time to stable isotopes.
C)All half-lives are long.
D)There is no known way to measure half-lives with any accuracy.
E)both A and B

Question

Quizplus · Accepted Answer

The combination of both options A and B make radioactive material problematic. Option A states that there is no known way to shorten a half-life, meaning that once a substance becomes radioactive, it will remain so until it naturally decays over time. Option B states that radioactivity is limited by the natural decay-time to stable isotopes, meaning that the decay process cannot be accelerated. Therefore, radioactive material can be hazardous for long periods of time, causing potential harm to living organisms and the environment.
