The database is stored in a dedicated server of the Centre de Calcul de Lyon. It is built using MySQL system combined with php scripts which allow to communicate from the web page to the database. Database on radiopurity of materials A reminder: WP4-Pia Loaiza, Feb Measurements from gamma spectroscopy ICPMS Neutron activation analysis Radon emanation

WP4-Pia Loaiza, Feb Between 1- 4 October 2006 the 2 nd Topical Workshop In Low Radioactivity Techniques was held in Aussois. Low background screening facilities Radio-isotopes of concern in low background detectors: Pb/Bi/Po-210, Xe,Kr,Ar Radon reduction Neutron backgrounds Application in other disciplines Topics: Proceedings to be published by AIP Conference Proceedings
