1 sie 2024 · Uranium is a naturally occurring radionuclide with chemical toxicity, derived from deposits formed through complex processes. In recent years, uranium utilization activities have increased uranium levels in the soil environment, posing serious threats to soil quality, food safety, and human health.
Uranium is a silvery-gray metal and a radioactive element with atomic number 92. The most common isotope in natural uranium is uranium-238, which decays by alpha emission with a half-life of 4.468 billion years. Learn more about uranium's history, chemistry, applications and environmental impact.
