Calibration of Radiation Measurement Instruments
The Secondary Standard Dosimetry Laboratory (SSDL) is the national laboratory in the field of calibration of ionizing radiation detectors. It was established in 2007 and it provides calibrations in terms of air kerma, personnel equivalent dose Hp(10), ambient dose equivalent H*(10) in the fields of radiation protection.

Radiation survey detectors such as survey meters and dosimeters are usually used to assess any possible leak of radiation from relevant equipments or through different kind of shieldings.



These detectors need to be calibrated systematically once per year in order to ensure the accuracy of their results within acceptable level of uncertainty. The SSDL is equipped by an X-Ray system with a 250KV X-ray tube and a Cs-137 irradiator, and standard dosimeters. The reference standards dosimeters are traceable to the IAEA Primary Standard Dosimeter Laboratory.
Individual Dose Management
The IMS (Individual Monitoring System) laboratory is monitoring ~ 3500 workers dealing with regulated areas. The laboratory is using TLD (thermo-luminescence dosimeter) for both whole body assessment and area monitoring purposes. Additional TLD can be delivered for interventional X-ray to assess of the extremity dose.
The IMS laboratorys performance has been demonstrated through its participation in many proficiency tests, with highly satisfactory results especially at high doses. In addition, the development of quality control and quality assurance system will lead the laboratory to generate high reliability results and then to be well prepared for accreditation according to ISO 17025.
Quality Control of X-ray equipment
Quality control of X-ray equipment is an important step in the Quality Assurance Program. This later is a prerequisite for any license request dealing with practices involving X-ray equipments.

The department is covering the QC of such equipment and delivers official certificates in this regards that are used for the license request as well as for the accreditation demand. The QC is performed on a yearly basis. The number of QC certificates delivered for X-ray facilities all around the country is ~ 500 per year.

Workplace Monitoring
Workplace monitoring achieves and maintains an acceptable protection of the working environment from radiation hazards. Monitoring includes measurements and radiological assessment of the obtained results.

A workplace monitoring program is implemented by the LAEC to assure radiation safety for all relevant practices and in different kinds of facilities. The workplace monitoring is also a prerequisite safety measure for licensing and accreditation processes of any practice dealing with ionizing radiation.

More than 400 workplace monitoring missions are assured yearly by the department.
