Description

The radioactive iodine-129 (129I) is an important radionuclide for environmental assessment because it has a long half-life and is accumulated in the thyroid gland in humans. A new analytical technique by Microwave Induced Plasma Mass Spectrometer (MIP-MS) was applied to the determination of 129I in soil samples. In environmental samples, a large amount of matrix elements are present. Therefore, the matrix elements were eliminated by ashing at 1000degC, and iodine isotopes were trapped by an activated charcoal and finally extracted by 10% tetramethylammonium hydroxide (TMAH). The concentration of 129I in a soil samples were compared between results of neutron activation analysis and MIP-MS method. The results showed an excellent agreement. (author)
