Question
**Problem 5: Radioactive Decay of Cesium-137** Following the Tohoku earthquake and the tsunami which greatly damaged the Fukushima power plant on March 11, 2011, it was announced that extremely high levels of cesium-137 were released. This isotope has a half-life of 30 years. In the wastewater discovered in a pit next to the reactor site, an estimated total of 100 kilograms of radioactive substances was detected. **Question:** How much cesium-137 would remain after 120 years? **Options:** - A. 6.25 kg - B. 19.15 kg - C. 38.85 kg - D. 84.09 kg **Note:** There are no graphs or diagrams associated with this problem. The question focuses on calculating the remaining amount of cesium-137 based on its half-life over the given time period.
