Today, nuclear mechanics are everywhere. Lights, signals and even the sun are all forms of radiation in frequency. X-Ray machines, nuclear medicines and radiation therapies are all huge parts of the medical field. Chemotherapy is treatment for cancer patients via nuclear radiation. Moisture, thickness and volume are all factors manufacturers taken into mind when manufacturing; radioactive materials help measure it. Many lights today in public and military use involve radioactive materials such as neon or tritium. Radon is a common paint ingredient. Nuclear radiation is used in agriculture to increase the lifespan of plants and kill invading insects. Archeologists use carbon dating to estimate what age a certain item is by identifying the amount of decay that a certain material has radiated. Even common household appliances such as smoke detectors use nuclear mechanics in them. Nuclear weapons are still produced and materials derived from radioactive materials are used for vehicles and gear for the military. Over a thousand nuclear power plants are active around the world.
