Which outcome results when an industrial radiography source exceeds lifespan?

💡 Explanation

Radiography source decay causes decreasing specific activity; therefore, radiographic contrast progressively degrades because less penetrating radiation reaches the detector. This differs from shield degradation, where dose rate increases rather than contrast diminishing.
