Question

When studying radioactive material, a nuclear engineer found that over 365 days, ( 1,000,000 ) radioactive atoms decayed to 974,384 radioactive atoms, so 25,616 atoms decayed during 365 days. A. Find the probability that a given radioactive atom will decay within 365 days. B. Find the half-life of the radioactive material.

Answer 1

Step-by-step explanation:

974,384 =1,000,000 x (1/2) ^1 / h
h = 26.7 or round 27 years
