The photochemical reduction of neptunium in aqueous perchloric acid is complicated because it must compete at times with the oxidation processes caused by the HCIO. In contrast to the... 

MO2 ions are formed by the four elements from uranium to ameridum. For uranium, the hexavalent oxidation state is the most stable one. Though easily reduced, it is also prominent in the chemistries of neptunium and plutonium. Ameridum(vi) is a very strong oxidizing agent. As the ameridum isotopes available are quite radioactive, a steady radiation-induced reduction of AmO occurs in aqueous solution, as soon as a strongly oxidizing system is not present [19].
