By mass spectral analysis, a sample of strontium is known to contain 2.64 10 10 atoms

Question:

By mass spectral analysis, a sample of strontium is known to contain 2.64 × 10¹⁰ atoms of ⁹⁰Sr as the only radioactive element. The absolute disintegration rate of this sample is measured as 1238 disintegrations/min.

(a) Calculate the half-life (in years) of ⁹⁰Sr.

(b) How long will it take for the disintegration rate of this sample to decline to 1000 disintegrations/min?
