Abstract
Cosmic rays interact not only with the atmosphere, but also with material at the surface of the Earth. Thus C-14 can be produced directly in a rock surface by the effect of cosmic-ray neutron effects. The goal of the research is to develop the capability of the Hertelendi Laboratory for Environmental Sciences (HEKAL) in the field of cosmogenic radionuclides produced in situ by the action of cosmic radiation. Our aim is to construct a small line for the extraction of cosmogenic C-14 from quartz, making a system compatible with the online capabilities of the new MICADAS accelerator mass spectrometer (AMS) at HEKAL in Debrecen. We have tested the chemical blank level, cross contamination effect and reproducibility of MICADAS gas ion source application in in-situ rock surface exposure dating.
