The center has a blockhouse and a room dedicated to the radiographic shots, they meet the safety standards of protection against radiation, they are periodically inspected by the Commission in atomic energy.
Only the head of the department authorizes qualified personnel access to the the blockhouse.
The center offers these researchers the opportunity developed research projects in ray-x and gamma; the source movement is coordinated with the Commission in atomic energy; moreover, they are also used by our common servicesfor to the state economy profile.
The Quality Department and Radiation consists of:

  • Radiation of service;
  • Quality Section;

The radiation protection service regularly checks the conditions of storage of the radioactive material and ensures its management. In addition, the services of the Commission for Atomic Energy (COMENA) conduct regular inspections of the blockhouse. This type of inspection is also programmed by the International Atomic Energy Agency (IAEA).
Safety and security in the use of radioactive sources are a major concern for the center; the radiation protection service ensures minimize and eliminate risks to the technicians, the public and the environment.
Our radioactive materials transport vehicles comply with the regulations; each has its own conformity certificate: it is issued after a rigorous control by the services of Algiers nuclear research center (CRNA).
The storage of radioactive sources is subject to the requirements of safety standards in the field of radioprotection a series of dose rate measure is performed inside and outside of our blockhouse.
Regarding the radiology under X-rays; generators are used according to the manufacturer’s instructions and recommendations, handling of radiation is done only after authorization of the service, which ensures the markup and defines the work areas.
Each technician where researcher working on gamma or X should be an internal training courses radioprotection.
Each user to a dosimetric film, he carries with him during his manipulations, it has a dose counter, at the end of each day and he raises his value and carries on its monthly dosimetric sheet.
The service records the dosimetric sheet and verifies information with those provided by the CRNA.
The Department has established procedures for traceability of all radioactive materials leaving the blockhouse to their backs, it sets up procedures based on regulations and standards for sources for transport, storage and use radioactive
These procedures concern:
  • The dose rate measurement;
  • The movement of apparatus;
  • the movement of containers;
  • The various operations.
Also, the Quality Department and Radiation Protection works closely with common services and research divisions to develop and improve radiographic techniques under-x.
Furthermore, it is noted that the staff of Quality and Radiation Protection Department called to work in the presence of ionizing radiation received adequate training in radiation protection and regularly attends training courses in the field.
Services Department
  • Radiation Protection Service
  • Quality Section
Radiation Protection Service
Radiation protection service includes an engineer in charge radiation protection in the center and technicians in charge the security of radioactive sources.
The engineer disseminates safety information related to the use, transport and storage of radioactive sources. This ensures that the content of the emergency plan is well understood by users of radioactive sources, manages dosimeter in the center, it monitors staff training in radiation protection and follows the calibration of radiation detectors.
The head of the security of radioactive sources is in charge of organizing the physical protection of radioactive sources in the center, keeps up to date source movement records and the list of persons authorized to access the blockhouse.
The radiation protection service maintains the inventory of radioactive sources.
Quality Section
This section depends in other one of the quality service which works directly with the direction of the center.
The main mission of this section is to develop a quality approach in the field of radiation protection, particularly through the establishment of a system for monitoring and risk assessment of radiation.
One of the main tasks in the quality section is to check all the technicians on devices:
  • Audits of individual and collective facilities of radiation protection;
  • Standardize the places of work.
