The Cerberus test (control experiment with radiation of the Belgian repository for underground storage) aims at simulating the near-field effects in an argillaceous environment of a vitrified high level waste (HLW) Cogema-type canister after 50 years' cooling time. The present report details the survey of the induced near-field effects which was carried out in the underground laboratory in clay by means of an extensive instrumentation programme and included the monitoring of temperature, dose rate, interstitial and total pressure. Tests were also performed to determine the heat and the hydraulic transfer parameters, pH/Eh and hydrogen and methane content. A migration experiment with a cocktail of 241-Am and 99-Tc ran from March 1993 until October 1994 in the near field of the Cerberus test.
