A more open future for nuclear research
A growing number of institutional, national, and funder mandates are requiring researchers to make their published work immediately publicly accessible, through either open repositories or open access (OA) publications. In addition, both private and public funders are developing policies, such as those from the Office of Science and Technology Policy and the European Commission, that ask researchers to make publicly available at the time of publication as much of their underlying data and other materials as possible. These, combined with movement in the scientific community toward embracing open science principles (seen, for example, in the dramatic rise of preprint servers like arXiv), demonstrate a need for a different kind of publishing outlet.

Tritium is an isotope of hydrogen, produced in the upper level of the atmosphere. It enters the water cycle after its oxidation and through the precipitation. The measurement of tritium concentration in rainwater is of great importance because it can be used for hydrology investigations such as the recharge mode or the vulnerability of aquifers.For this purpose, rainwater samples were collected for a period of 16 months from October 2002 to January 2004 from a sampling station at Ioannina, northwestern Greece. Each sample was filtered and measured without any further treatment for tritium activity, using a super low-level background, liquid scintillation analyzer. Five mL of the sample were mixed with 15 mL of scintillation cocktail, specially designed for low-level tritium measurements and its beta activity was measured for 500 min.Results show that during the sampling period, the tritium concentration varied up to two fold, increasing during the spring and summer months. The measured tritium concentrations in rainwater, which ranged from 9 ± 4 to 23 ± 5 TU, can be used for local hydrology studies.
