Abstract (sommario):

The cyclotron-based ¹⁰⁰Mo(p,2n)⁹⁹mTc reaction has been proposed as an alternative method for solving the recent shortage of ⁹⁹mTc, which is the most commonly used radioisotope in nuclear medicine. With this production method, however, even if highly enriched molybdenum is used, various radioactive and stable isotopes can be produced simultaneously with ⁹⁹mTc and they may affect the diagnostic outcome and radiation dosimetry in human studies. The objective of this thesis was to investigate the feasibility of the cyclotron-based production of ⁹⁹mTc. Towards this aim, theoretical predictions and

Abstract (sommario):

Quantification of tin isotopes in environmental samples, particularly the radioactive 126Sn, is important for processes such as the biomonitoring of organotin species, long-term nuclear waste storage and treatment planning. The detection of 126Sn by mass spectrometric methods is, however, hampered by the presence of the stable 126Te isotope. Therefore, separation of tin from tellurium is crucial to minimize isobaric interferences that limit the quantification of 126Sn by Accelerator Mass Spectrometry (AMS) and other instrumental techniques. In the present study, three major accomplishments are

Abstract (sommario):

Introduction The embrace of PET by medical clinicians has been reluctant (ΔT ≈ 20 yr) primarily due to the scale of the infrastructure that is needed. The capital cost of a cyclotron (≈ 106 USD) is now dwarfed by the demand for compliance to recent regulatory standards. This is a recurring expense, not only imposing an order-of-magnitude increase in staffing and operating costs, but damping the enthusiasm of researchers recalling the brisk pace of research in earlier days. Now an academic site, with little interest or opportunity to scale up production for wider distribution, is burdened by th

While process investigations at smaller scales (< 10km2) have been important in establishing the influence of topography and soils on runoff generation, more research at larger spatial scales is needed, since it is at such scales where important water management decisions are
