A range of complementary radionuclide proxies in sediments of the southernmost Atlantic Ocean over the past 140,000 years indicate that glacial periods were characterized by greatly increased fluxes of biogenic detritus out of surface waters. This in

Particle reactive elements are scavenged to a higher degree at ocean margins than in the open ocean due to higher fluxes of biogenic and terrigenous particles. In order to determine the influence of these processes on the depositional fluxes of10Be a

Stable and radioactive products of cosmic ray interactions with extraterrestrial matter provide a record of the history of small bodies in the solar system and of the cosmic radiation itself. A basis for an improved understanding of these cosmogenic

In order to provide thin-target cross sections as a basis for model calculations of the interactions of solar and galactic α-particles, irradiation experiments with α-particles were performed at the injector cyclotron at PSI/Villigen ( E max = 119.

With a half-life of (104±5) kyr, which lies between the one of 14C and 36Cl, 41Ca is of interest for studies of the irradiation history of extraterrestrial materials. The determination of 41Ca by activity measurement is not easy because it purely de
