Question
Explain why a radioactive isotope with a very long half-life can increase long-term hazard.
Answer
A radioactive isotope with a very long half-life remains radioactive for an extended period, leading to prolonged exposure to radiation. This can increase the risk of harmful effects, such as cancer, in individuals who are exposed over time.
Explanation
This question tests the understanding of the relationship between half-life and radiation hazard. A strong answer demonstrates knowledge of how long-term exposure to radiation can pose health risks.
Common mistake
Long Half-Life Misunderstanding
Students often confuse a long half-life with a low hazard, thinking it means less risk over time.
Emphasize that a long half-life means the radioactive material remains active and potentially hazardous for a longer duration, increasing long-term risk.
