Naturally occurring technetium occurs as a spontaneous fission product in uranium ore or by neutron capture in molybdenum ore.Up to 2008,approximately 1.6 PBq(2.5 t)of 99Tc has been released to the environment through nuclear fuel processing and nuclear weapons testing since 1940’s.Technetium is very mobile in soils,ground and surface waters.Because technetium behaves as a nutrient analogue and
