The past 5000 years history of solar modulation of cosmic radiation from 10Be and 14C studies ...
10Be is produced in a similar way as 14C by the interaction of cosmic radiation with the nuclei in the atmosphere. Assuming that the 10Be and 14C variation are proportional and considering the different behaviour in the Earth system, the 10Be concentrations in ice cores can be compared with the 14C...
