Neptunium is dangerous due to it's radioactivity- it is similar to Uranium or Plutonium. It is likely to be chemically poisonous, but the radiation effects outweigh the chemical hazards. Neptunium is rarely found in a pure state, and results from decay of other radioactive materials, such as Plutonium and Americium.
