Question

A) state what is meant by the decay constant of a radioactive isotope. B) show that decay constant lambda is related to half life in 9702

Answer 1

Explanation:

Constant quantities: The half-life—t1/2, is the time taken for the activity of a given amount of a radioactive substance to decay to half of its initial value; see List of nuclides.

The decay constant— λ, "lambda" the reciprocal of the mean lifetime (in s−1), sometimes referred to as simply decay rate.
