Question

HOW IS THE HALFLIFE OF A RADIOACTIVE ISOTOPE DETERMINED

Answer 1

Explanation:

The half-life is then determined from the fundamental definition of activity as the product of the radionuclide decay constant, λ, and the number of radioactive atoms present, N.

Answer 2

Explanation:

The half-life is then determined from the fundamental definition of activity as the product of the radionuclide decay constant, λ, and the number of radioactive atoms present, N. One solves for λ and gets the half-life from the relationship λ = ln2/T1/2
