    • Calibration of Radiation Measuring Instruments

      Calibration of Radiation Measuring Instruments

      SSDL is the national centre for the calibration of radiation measuring instruments for dosimeters used in radiotherapy and for the radiation protection . Requirement for calibration of radiation measuring instrument is enshrined under the Atomic Energy Licensing Act 1984 (Act 304), Radiation Protection (Basic Safety Standards) Regulations 1988 (amended 2010). The SSDL Calibration Laboratory has been accredited in accordance with the MS ISO/IEC 17025:2005 standard since July 2004. All measurement and calibration are traceable to the primary and international standard laboratories.

    • Personal and Area Dosimetry

      SSDL also offering services for individual and workplace monitoring. This service is important for assessment of the exposure dose of radiation workers as well as monitoring of the workplace safety with particular concern on the ionizing radiation hazard. There are two types of dosimeter offered by SSDL namely film badges and Thermoluminescence dosimeters (TLD). Both dosimeters can be used for whole body assessment or area monitoring.

    • High Dose Dosimetry for Industrial Application

      Radiation processing technology involves high-absorbed dose in the range between 0.1 to hundreds of kilogray (kGy). The reliability and accuracy of the dosimeter system play a vital role in the quality assurance and process control of industrial radiation processing. SSDL provides ceric-cerous and ferrous sulphate (Fricke) dosimeters for process control and quality assurance in radiation processing, utilising Cobalt-60 gamma irradiators. The radiation dose measured by ceric-cerous dosimeters can be evaluated using a simple equipment such as the electrochemical potentiometer cell while evaluation for radiation dose measured by Fricke dosimeter is carried out using UV spectrophotometer.  Calibration for high dose dosimeter is accredited in accordance with the MS ISO/IEC 17025 standards since May 2011.

    • Nuclear Forensic

      Nuclear Forensic is defined as the examination of nuclear or other radioactive materials or of evidence contaminated with radionuclides in the context of international or national law or so-called nuclear security. Nuclear forensic is a multidisciplinary field including radio-analytical chemistry, nuclear and radiochemistry, reactor physics, nuclear engineering, process engineering, material science, geology etc. The nuclear forensic analysis includes categorization, characterization, nuclear forensic interpretation and reconstruction. Particularly, nuclear forensic evidence helps law enforcement and intelligence agencies work toward preventing, mitigating and attributing a nuclear or radiological incident. The finding maybe required as evidence in a court of law.

      The Nuclear Forensic Center, Malaysian Nuclear Agency (Nuklear Malaysia) has been developed to assist in the investigation of criminal incidents and emergencies involving nuclear and radioactive materials. Serves as a reference center and guide in nuclear forensic analysis and to ensure the efficient and effective use of laboratory facilities in conducting nuclear forensic investigations. The center is formed under two main plans, namely at the national level in the Key Focus Sector for Nuclear Safety and Security contained in the plan under the National Nuclear Technology Policy (2021 -2030) and also contained in Strategy 11 Malaysia Nuclear Vision to Empower Forensic Centers National Nuclear and Forensic Studies in Industry.

      The Nuclear Forensic Management System is an integrated operating procedure throughout the agency. The Nuclear Forensic Committee (JKFN), Nuklear Malaysia has the role to plan activities, develop and update the latest regulations and ensure the implementation of each plan. The Health Physics Group under the Radiation Safety & Health Division which is also a member of JKFN acts as the secretariat and will act as the coordinator for nuclear forensic cases and provide technical reports to the designated authorities. Technical laboratories and experts will perform nuclear forensic analysis, interpret and provide the results to the secretariat.

      These laboratories will be involved in nuclear forensic case:

      • Radiochemistry and Environment Laboratory (RAS)
      • Analytical Chemistry Application Laboratory (ACA): will be supported by Reactor Group
      •  Material Technology Group (MTEG)
      • Micro Computed Tomography Laboratory (MicroCT)
      • Transmission Electron Microscope Laboratory (TEM)
