So far we have measured E3 transitions in three nuclei, 103 Rh, 111 Cd and 134 Cs; and M4 transitions in six nuclei, 119 Sn, 125 Te, 127 Te, 137 Ba, 193 Ir and 197 Pt. back to the detector. The large peak that we see to the extreme left is due to internal conversion, which happens mostly because the excited 137Ba nuclei has a comparatively long half-life of 2.55 minutes. Absorption Coefficient of Lead and Tin For calculating the absorption coefficient, we used layers of lead and tin between different sources (cpm/(γ/sec)) and the gamma emission yield of Cs-137 (0.85). The intake amount (Bq) is calculated by dividing the above value by the whole-body retention rate at the elapsed days from assumed intake date to measurement date. The effective dose is then calculated by multiplying the above value by the effective dose coefficient of Cs-137.

94.7% of beta decays lead to an excited state of the nucleus : 85.1% return to the ground state by emitting an energetic 661.57 keV gamma, while 9.6% returns to stability through internal conversion. Spectra have also been obtained for the prompt luminescence observed when feldspars are stimulated using a 137 Cs internal conversion (beta) source, which forms part of the RL dating instrument (see Section 7.10 and Fig. 7.16). Spectra were obtained using a spectrometer (200–800 nm) linked to a liquid nitrogen cooled CCD detector.

We have been testing the theory used to calculate internal-conversion coefficients (ICCs) by making a series of measurements of α K values with precision better than ±2%. So far we have measured E3 transitions in three nuclei, 103 Rh, 111 Cd and 134 Cs; and M4 transitions in six nuclei, 119 Sn, 125 Te, 127 Te, 137 Ba, 193 Ir and 197 Pt. back to the detector.
