1. Iodine Isotopes (129I and 127I) in the Baltic Sea : Tracer applications & environmental impact
Abstract : 129I is a radioactive isotope (T1/2= 15.7 million years) produced through natural and anthropogenic pathways, but the anthropogenic production is presently dominating the Earth’s surface environments. READ MORE

2. Iodine-Metal Surface Interactions under Severe Accident Conditions in a Nuclear Power Plant
Abstract : In the event of a severe nuclear reactor accident, iodine will be released from the fuel and eventually enter the containment. Radioactive iodine isotopes constitute both an acute and a long-term threat to humans, owing to its half-life and its accumulation in the thyroid gland. READ MORE

3. Iodine Isotopes and their Species in Surface Water from the North Sea to the Northeastern Atlantic Ocean
Abstract : Huge amounts of anthropogenic 129I have been and still are released to the environment through liquid and gaseous discharges from the nuclear fuel reprocessing facilities worldwide and in particular the ones in Europe. Most of this 129I signal has been accumulated in the marine environment which plays a major role in the iodine natural pool. READ MORE

4. Distribution, Sources and Environmental Pathways of Radioactive 129I in Fresh and Saline Water in the Baltic Region
Abstract : This thesis deals with distribution, sources and pathways of radioactive 129I (T1/2=15.6 My) in 54 rivers covering the Baltic region, precipitation (rain and snow) from southern, central and northern Sweden, and saline water from three depth profiles in the Baltic Sea and a surface water transect from the Baltic to the Kattegat.

5. Accelerator Mass Spectrometry of 36Cl and 129I : Analytical Aspects and Applications
Abstract : Two long-lived halogen radionuclides (36Cl, T1/2 = 301 kyr, and 129I, T1/2 = 15.7 Myr) have been studied by means of Accelerator Mass Spectrometry (AMS) at the Uppsala Tandem Laboratory. The 36Cl measurements in natural samples using a medium-sized tandem accelerator (~1 MeV/amu) have been considered. READ MORE
