1. 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

2. Anthropogenic 129I Traced in Environmental Archives by Accelerator Mass Spectrometry
Abstract : Since the beginning of the nuclear era, starting during the 1940s, large amount of radioactivity has been released into the environment. This thesis deals with the temporal and spatial distribution of the anthropogenic radioisotope 129I (T1/2= 15.7 Myr) in northern Europe. READ MORE

3. Biokinetics and radiation dosimetry of 14C-labelled triolein, urea, glycocholic acid and xylose in man. Studies related to nuclear medicine “breath tests” using accelerator mass spectrometry
Abstract : 14C-labelled substances have been used in biomedical research and clinical medicine for over 50 years. Physicians and scientists however, often hesitate to use these substances in patients and volunteers because the radiation dosimetry is unclear. READ MORE

4. Accelerator mass spectrometry of 129I and its applications in natural water systems
Abstract : During recent decades, huge amount of radioactive waste has been dumped into the earth's surface environments. 129I (T1/2 = 15.6 My) is one of the radioactive products that has been produced through a variety of processes, including atomic weapon testing, reprocessing of nuclear fuel and nuclear accidents.

5. Development of the Lund AMS Facility for the Detection of 59Ni – with Applications in the Nuclear Industry
Abstract : Accelerator mass spectrometry (AMS) is a highly sensitive method for counting atoms and it is used for detecting very low concentrations of both radionuclides and stable isotopes in small samples. The two major advantages of the AMS method are that the required amount of sample material is very small, but also that the efficiency is rather high, it takes less than an hour to analyse a sample.
