Answer 2

Answer:

Equation for decay law of radioactivity

Radioactive decay law: N = N.e-λt

Explanation:

Determine the amount of decay for the radioactive isotope

Calculations Using the First Order Rate Equation: r = k[N]

The rate of decay is often referred to as the activity of the isotope and is often measured in Curies (Ci), one curie = 3.700 x 1010 atoms that decay/sec

The rate of nuclear decay is also measured in terms of half-lives. The half-life is the amount of time it takes for a given isotope to lose half of its radioactivity. If a radioisotope has a half-life of 14 days, half of its atoms will have decayed within 14 days.
