How long will it take for the disintegration rate

By mass spectral analysis, a sample of strontium is known to contain 2.64x1010 atoms of Sr-90 as the only radioactive element. The absolute disintegration rate of this sample is measured as 1238 disintegrations per minute.

How long will it take (in years) for the disintegration rate of this sample to drop to 954 disintegrations per minute?
