Introduction

The use of radioactive sources is rapidly growing in Cameroun, especially in the medical and industrial sectors, where they are mostly use in radiotherapy, nuclear medecine on the one hand and, in the non destructive testing (NDT), well loging, nuclear gauges on the other hand.Since 2009 NRPA is carrying out the radioactive waste inventory.

I-OVERVIEW OF FACILITIES WHICH HAVE RADIOACTIVE WASTE

The Yaounde General HospitalThe Douala General Hospital Bonanjo polyclinic in DoualaA National civil engineering laboratory (LABOGENIE)The Nuclear Technology Section (NTS) of the

Institute of Geological and Mining Research (IRGM) The University of Yaounde

Among Facilities that have radioactive waste in Cameroon, we have:

III-Nuclear Legal Framework and related convention

-The law No 95/08 of the 30th January 1995 on RADIATION PROTECTION

-Decree No 2002/250 of the 31 October 2002 that creates organises and define the functioning of NRPA

-Law No 89/02 of the 29th December 1989 on Toxic and dangerous waste

-The BAMAKO Convention that ban the importation of dangerous waste in Africa, is on control the transboundary movements and on the management of waste in Africa.

Waste producers have the first responsibility for the management of their waste and this management is done under the control of NRPA

IV-RESPONSABILITIES AND ROLES OF INVOLVED ORGANISATIONS-LEGAL INSTITUTIONAL

STRUCTURE

V- POLICY AND STRATEGIES BEING DEVELOPED

With the IAEA assistance, Cameroon drafted in 2013 the national waste management policy and strategy. These documents are being discussed with other ministries like Mines and Environment before their adoption.

VI. PROBLEMS, NEEDS AND PLANS

Problems- National system of waste management not established- Insufficient trained staff

- Lack of legislation on waste management

- Contruction of a centralized spent sealed sources storage facility

- Drafting the legislation on waste management- Adoption of the waste management policy and strategy

NEEDS - trainings in WM of all facilities- Support for the construction and equipment of a

temporary waste disposal facility PLANS
