Neptunium is a radioactive metal that emits alpha particles, which are high-energy particles that can damage DNA and other cellular structures. Alpha particles are especially damaging to cells that are rapidly dividing, such as those in the gastrointestinal tract and reproductive organs. Neptunium can also be absorbed through the skin and respiratory tract.
The effects of neptunium poisoning depend on the amount of radiation that is absorbed. Low levels of radiation exposure can cause nausea, vomiting, and diarrhea. Higher levels of exposure can cause more serious health problems, including cancer, birth defects, and radiation poisoning.
There is no known cure for neptunium poisoning. Treatment focuses on managing the symptoms and preventing further exposure to radiation.
