International Workshop on National Registers of Radioactive Sources Vienna, Austria, from 20 to 23 by: Abbas Yassin Sudan Atomic Energy Radiation Safety Radioactive Waste unit

Introduction Use of radioisotope in Sudan started 65 years ago Radioactive waste management program started 1995 Act and regulatory authority are in place Radioactive waste management regulations enacted since 1998 Waste management facility established in 2000

Status of Waste Management Facilities Waste Facility consist of : Work area (lab) Cargo container (short-lived and/or waiting for conditioning) Storage Waste Storage lab Operating area container Storage 3 x 4 meter

WASTE MANAGEMENT FACILITY Laboratory Cemintation area Storage (1) Work bench Wash basin Extraction hood Door Storage (2) Door Door Door Door
