Total Absorption Spectroscopy measurements of the beta decay of Mo-103 and Tc-103, important contributors to the decay heat summation calculation in reactors, are reported in this work. The analysis of the experiment, performed at IGISOL with the new DTAS detector, show new beta intensity that was not detected in previous measurements with Ge detectors.
