Answer:
860.6 years.
Explanation:
The parameters given are;
Initial detector activity = 370000 alpha decays per second
Final detector activity = 93000 alpha decays per second
Formula for time to change in activity is given by the following relation;
![t_{93000} = \dfrac{-ln\dfrac{A}{A_0} }{\lambda} = \dfrac{-ln\dfrac{93000}{370000} }{5.08 \times 10^{-11}} = 2.72 \times 10^{10} \, seconds](https://tex.z-dn.net/?f=t_%7B93000%7D%20%3D%20%5Cdfrac%7B-ln%5Cdfrac%7BA%7D%7BA_0%7D%20%7D%7B%5Clambda%7D%20%3D%20%20%5Cdfrac%7B-ln%5Cdfrac%7B93000%7D%7B370000%7D%20%7D%7B5.08%20%5Ctimes%2010%5E%7B-11%7D%7D%20%3D%202.72%20%5Ctimes%2010%5E%7B10%7D%20%5C%2C%20seconds)
t₉₃₀₀₀ = 2.72 × 10¹⁰ seconds = 860.6 years.
