The marriage of these two fields is essential for a modern society. Beyond energy and medicine, they play a critical role in:

Scientists can replace a stable atom in a molecule with a radioactive one. Because the radioactive atom "glows" (emits signals), they can trace exactly how a drug moves through a human body or how a plant absorbs nutrients from the soil.

By controlling fission reactions (usually with Uranium-235), we generate massive amounts of heat to produce electricity without carbon emissions. 2. Radiochemistry: The Chemistry of Radioactive Materials

Using Radioisotope Thermoelectric Generators (RTGs) to power deep-space probes like Voyager and Mars rovers where solar power is insufficient.
