M.Sc <strong>Dissertation</strong>Appendix AThe present activity <strong>of</strong> used sourcesAt the present project the experiment were held in the period between mid <strong>of</strong> June andmid <strong>of</strong> August 2010. The activity <strong>of</strong> the known sources wasn‟t considerably changed,for better accuracy on the experiment the activity was calculated each day. Table A.1shows the energies <strong>of</strong> the gamma photons, along the decay probability are illustrated.Table A.1 Present activity <strong>of</strong> used sources and photons energySourceIsotopeEnergykeVProbability %Activity (kBq)14/06/10 21/06/10 28/06/10 5/07/10 12/07/10 19/07/10S175.PH137 Cs 661.67 85.10 259.022 258.908 258.794 258.680 258.566 258.452S317.PH60 Co1173.24 99.851332.50 99.9838.220 37.540 36.872 36.216 35.571 34.938S311.PH22 Na511.00 180.761274.53 99.9419.754 19.654 19.554 19.454 19.355 19.256121.78 35.67244.70 7.61344.27 29.00S259.PH152 Eu778.96 12.96152.482 152.332 152.182 152.033 151.883 151.734964.00 14.651112.05 13.691407.92 21.07K. <strong>Suren</strong> 36
