I ntroduction

Cameroon is lacated in Central Africa. It is bounded by Chad in the north, East by the Central African Republic, South by the Congo, Gabon and Equatorial Guinea, west by Nigeria. It covers and area of 475,440km² The climate of Cameoon in varied : tropical wet in the south and tropical dry in the north, Cameroo’s population is almost 20millions inhabitants Cameroon has 250 etnics groups, that implies the existence of 250 languages.

1 -Use and inventory of radioactive sources in Cam eroon

A N N R P N R P A

Ionizing radiation sources are used in:

• Medecine;
• Industry ;
• Research.
• Use of radioactive sources in Cameroon

1 -Use and inventory of radioactive sources in Cam eroon

A N N R P N R P A

radioactive sources are used in medecine for:

• Médical diagnostic,
• Therapy.

MEDICAL DIAGNOSTIC Imaging technique that use radioactive sources in Cameroon is:

• Scintigraphy (nuclear medecine).

A N N R P N R P A

Radioactive sources are used for the treatment of cancers. Practices encountered in general hospitals in Yaounde and Douala are:

• Teletherapy;
• Brachytherapy;
• Nuclear medecine.

RESERACH

Radioactive sources are used in some research institutes in Cameroon for calibration. These sources include:

210Pb, 109Cd, 57Co, 54Mn, 137Cs

Use and inventory of radioactive sources in Cam eroon Data on radiation sources were collected in 2009 and 2010 nation wide and registered in RAIS 3.0 . The updated data is currently running on RAIS 3.3.

2 - Regulatory fram ew ork

• Law n° 95/08 of 30th January 1995 on radiation

protection

• Decree n° 2002/250 of 31st October 2002 relating to the

creation, organization and functioning of the National Radiation Protection Agency (NRPA)

Created in 2002 in application of Law n° 95/08 of 30th January 1995 on radiation protection , the NRPA started functioning in 2007. In January 2010, a new Director General was nominated.

• Decree n° 2007/102 of 13th April 2007 appointed the

Board Chairman of NRPA;

• Decree n° 2007/103 of 13th April 2007 appointed the

Director General of NRPA;

• Decree n° 2007/297 of 05th November 2007 appointed

members of Board of Directors of NRPA;

• Decree n° 2010/024 of 28th January 2010 nominated the new Director

General of the NRPA.

2 -Regulatory fram ew ork

The following regulations initiated by NRPA were validated (visas) by the Service of the Prime Minister, then signed and gazetted by Minister of Public Health in June 2013:

• 1. Arrêté N° 1150 /A/MINSANTE on Work Place Monitoring
• f 11 June 2013 laying down the conditions and signaling
• f

supervised and controlled areas and especially restricted and prohibited zones as well as imposed hygiene, safety and maintenance rules.

• 2. Arrêté N° 1151 /A/MINSANTE on Dosimetry Monitoring of

11 June 2013 laying down procedures of medical and

• ccupational monitoring of workers and patients exposed

to ionizing radiation.

• 3. Arrêté N° 1152 /A/MINSANTE on Licensing and Practices

Modalities for X Ray Generators of 11 June 2013 laying down procedures for possession, use and handling of devices emitting X-rays in hospital.

• to regulate all ionizing radiation sources as w ell as the

protection of people and environm ent against ionizing radiation hazards.

• to

establish

adopt, in consultation and, w here appropriate, in collaboration w ith com petent authorities, standards

• f

safety for protection

• f

health and m inim ization of danger to life and property ( including such standards for labour conditions) , and to provide for the application of these standards to its ow n operations as w ell as to assisted operations

3 - NRPA: structure and organization The NRPA is administrated by a Board of Administrators (representatives from the Presidency, the Prime Ministry and 8

• thers ministries). The Director General supervises the daily

activities of NRPA and reports to the Board.

4 - Regulatory body activities

I- AUTHORIZATION

Within the framework of its missions, the National Radiation Protection Agency (NRPA) shall authorize the use of radiation sources as well as the related activities, and approve workers under ionizing

• radiations. In order to achieve these missions, the NRPA set up a system
• f notification and authorization which is based on:
• the legislative framework and lawful made up mainly of law n° 95/08 of

30 January 1995 on radiation protection, and the decree n° 2002/250 of 31 October 2002 to set up, organize and regulate the functioning of the National Radiation Protection Agency;

• technical document TECDOC 1525 of the International Atomic Energy

Agency;

• practices met in Cameroun namely: radiotherapy, nuclear medicine,

medical radiography, industrial radiography, well logging, nuclear gauges.

II- Technical Control (Inspection and Quality Control) Staff were trained through IAEA Technical Cooperation projects of RAF9038 , RAF 9042 and CMR 9004. The system is fully operational since 2012 with annual program put in place. Guides and Checklists have been developed following TECDOC 1526 with over two Hundred (200) regulatory controls carried out in the following facilities: radiotherapy, nuclear medicine, radio diagnostic, well logging, and Non Destructive Testing.

with th th the Mi e Ministry of Tran ansport (MI (MINT) an and th the e oth ther with Mi Ministry of Public c Heal alth (MINSANTE). ).

• The first concerns technical assistance to MINT within the

framework of the implementation of the MOU signed in November 2010 between MINT and Department of Energy of USA relating to the project MEGAPORT INIATIVE on illicit traffic of nuclear materials and radioactive substances ;

• The second signed with MINSANTE in 2011 is relating

to NRPA assistance towards upgrading radiation protection in public hospitals;

• MoU between Custom and NRPA is on-going.
