Question

Which of these statements would best explain the problem encountered with nuclear waste disposal? A) The isotopes have a long half-life and only remain radioactive for a long time period. B) The isotopes have a short half-life and only remain radioactive for a long time period. C) The isotopes have a long half-life and only remain radioactive for a short time period. D) The isotopes have a short half-life and only remain radioactive for a short time period. 
ANSWER IS A)

Answer 1

That's right, the correct answer is
A) The isotopes have a long half-life and only remain radioactive for a long time period

The half life of an isotope is the time it takes for the amount of the sample to reduce to half of its initial value. If an isotope has a long half-life, it means it takes a long time to reduce down to a significant level, so it will remain radioactive for a long time period.
