Radioisotopes of certain elements, whether from nuclear activities or naturally occurring, are found at exceedingly low concentrations in our environment. They can be useful as tracers in geological and biological systems, but can also pose a radiation hazard. The objective of my research begins with the development of techniques to measure their low concentrations using the unique capabilities of an accelerator mass spectrometer, which allows very low radioisotope concentrations to be measured in very small samples. We will then employ these techniques to address the behaviour of radioisotopes in the environment and their use as radio-tracers in biomedical applications.

某些元素的放射性同位素，无论是来自核活动还是自然产生的，在我们的环境中都以极低的浓度存在。它们可以作为地质和生物系统中的示踪剂，但也可能造成辐射危害。我的研究目标始于使用加速器质谱仪的独特功能测量其低浓度的技术开发，该技术允许在非常小的样品中测量非常低的放射性同位素浓度。然后，我们将采用这些技术来解决放射性同位素在环境中的行为及其在生物医学应用中作为放射性示踪剂的用途。
