Origin of (3)He in the Earth is a mystery. Lacking a production mechanism, scientists assume (3)He was trapped in the Earth, when the Earth was formed. In contrast to this assumption, we have found (3)He and (3)H concentrations in excess of the atmos

This paper summarizes the observation results of mantle tritium (3H) in two volcanic lakes, Lakes Nemrut (Turkey) and Laacher (Germany). The presence of excess 3H in the lakes can be explained as material released from mantle source because of the co

A new attempt has been made for the re-measurement of the half-life of 79 Se. We made two major improvements over our earlier 79 Se half-life determination (Nucl. Instr. and Meth. B 123 (1997) 403). Firstly, the half-life of 79 Se was measured relati
