1.	What is the time during which one half of a number of radioactive species decays or one half of their activity ceases?(a) Half Life(b) Super critical state(c) Semi life(d) Critical lifeI got this question in an online interview.This interesting question is from Atomic Structure topic in section Nuclear Power Plant of Energy Engineering
Answer» Correct OPTION is (a) Half LIFE Easiest explanation: Half life is the time during which one half of a number of radioactive species decays or one half of their ACTIVITY ceases. It is also USED to characterize any type of EXPONENTIAL and Non-exponential decay.
