- Abstract:
- 32-Si is a radioactive isotope produced by the action of cosmic ray derived neutrons on atmospheric Ar, and subsequently deposited in terrestrial and aquatic systems. With a half life of approximately 140 years, and radioactive decay by beta decay through 32-P, it has important applications for dating and tracing environmental process over the 100-1000 year timescale. Fields of application include climate reconstruction, sedimentology glaciology, and hydrology. Present global capabilities for 32-Si are limited by the extremely low levels of radioactivity from environmental samples, leading to extremely long measurements using conventional detectors. This project will develop a novel multi-sample detector array, incorporating state of the art background reduction techniques, and associated sample handling facilities to improve both the quality and throughput of 32-Si analysis. Initial applications will be to sedimentary and aquatic systems, but it is envisaged that a broader range of important applications to NERC themes will emerge following the initial development.
