N2  - An ultra-compact and unshielded spectrometer for analysis of atmospheric radioxenons has been developed. This system works at ambient temperature and has a 58 cm<sup>3</sup> inner active volume. Atmospheric radioxenons activities are determined with electron/photon coincidence technique using both NaI(Tl) detector and large pixellized Si-PIN detector. The performances of the detection system without shielding in terms of Minimal Detectable Activities are below 65 mBq for a 12 h acquisition, for all radioxenons of interest. An enhanced version of the prototype presented here is already under development: the Mobile Analyzer for Radioactive Gases OuTflows (MARGOT) system.<br><br>Copyright © 2019 Elsevier Ltd.
