"The study of long-term solar activity variations in the past requires the use of radioisotopic\r\ndata planetary reservoirs. At the Laboratory of Monte dei Cappuccini in Torino\r\n(IFSI-Torino, INAF) for many years we have been studying radioisotopes in meteorites,\r\nbecause their production, which is related to galactic cosmic ray flux in the heliosphere, is\r\nanticorrelated with the heliospheric magnetic field variations. We have developed very sensitive\r\ngamma detection techniques, in particular to measure 44Ti activity in meteorites; due\r\nto its half-life (t1=2 = 59:2 years), this radioisotope is an ideal index to reveal the imprint of\r\nsolar activity variations on the centennial scale. Recently we have improved the spectrometer\r\nby a new multiparametric acquisition system, which allows to extract efficiently the 44Ti\r\npeak from the natural background."^^ . "2010" . "Suppl." .
