Decay constant of a radioactive element is the reciprocal of the time during which the number of atoms left in the sample reduces to 1//e times the original number of atoms in the sample.
Decay constant, proportionality between the size of a population of radioactive atoms and the rate at which the population decreases because of radioactive decay. The time required for half of the original population of radioactive atoms to decay is call
衰变常数(λ)是放射性核素单位时间内单个原子核发生衰变的概率,由核素本身性质决定且保持恒定。其数值与半衰期成反比(τ=0.693/λ),在核医学、环境保护和地质测年等领域具有重要应用价值。以下从定义特性、计算关系、实际应用三个维度展开说明。 一、衰变常数的核心特性 衰变常数的本质是概...
