A radioactive substance decays at a rate of 12% per year. If the initial mass is 250 grams, what will the mass be after 10 years?

**Northern Evolution Growth: Understanding Radioactive Decay and What 250 Grams Becomes After a Decade** Why are more people exploring how radioactive substances change over time—especially with a steady 12% annual loss? From advanced medical imaging to energy innovation, decay is a quiet yet powerful process shaping technology, health, and industry. For those curious about real-world calculations and natural processes, understanding radioactive decay offers valuable insight—like how 250 grams gradually diminishes over a decade, a topic gaining quiet traction across scientific curiosity circles and practical life planning. When a radioactive substance decays at 12% per year, 88% remains after each year—meaning gradual but measurable reduction. For a starting mass of 250 grams, this decay rate transforms the material into progressively less mass over time. This isn’t a sudden change but a steady evolution—something people want to understand clearly, especially as applications in medicine and safety grow. ### Why Radioactive decay of 12% per year Is Gaining Interest in the U.S.
