Nuclear Analytical service

PDF Print Email

The Life Science Division is mainly responsible for providing efficient and effective analytical services based on Nuclear Analytical Technique in Compliance with international standards to fulfill customer satisfaction, serving the nation through utilization of Nuclear Technology for Agriculture, Health and Environmental sector’s for Socio-economic development in the country and becoming a Reference Laboratory for Nuclear Analytical Techniques with International acceptance.

The major fields of the Division are:

  • Nuclear Analytical Services for Environmental, Health, Commercial and Agricultural Sectors - The specific objective of Nuclear Analytical services Section is to establish a reference laboratory for nuclear analytical techniques in Sri Lanka and this laboratory provides professional and standardized services for Sri Lankan exporters, importers, researchers and other customers.

  • Use of Nuclear Technology for Agricultural Sector for enhancing the productivity and Quality - The Specific objective of the agriculture section is to promote the nuclear technology for agricultural activities to meet the national requirements.

  • Use of Nuclear Technology for R & D activities in Environmental and Health sectors -

Nuclear Analytical Testing (NAT) Capabilities

This Division has three major Nuclear Analytical Laboratories namely Low level counting lab for gamma spectrometry, Low level counting lab for alpha and beta spectrometry and X-ray Fluorescence analytical laboratory. Low level counting lab for gamma spectrometry has already been accredited for gamma analysis of selected isotopes in 2006. The XRF laboratory has also accredited for several selected analysis in 2010. The laboratories adopt the ISO 17025 international standards.

Low Level Gamma Counting Laboratory

This laboratory of the AEA is the only laboratory for radioactivity measurements which has obtained national accreditation in compliance with ISO IEC 17025 from National Accreditation Board. It uses equipment calibrated according to international standards and employs skilled and trained staff with good professional practice to achieve the goals. Major activities are as follows.

  • Radioactivity measurements in Food( Milk powder etc) and Agricultural products (Tea, Coconut etc)
  • Environmental Radioactive assessments.

X-Ray Fluorescence (XRF) Laboratory

This laboratory has both EDXRF (Energy Dispersive X ray fluorescence) and TXRF (Total Reflection XRF) facilities to analyze elemental composition/concentration qualitatively as well as quantitatively in varies sample matrices. Using EDXRF technique heavy metal concentrations in food and other materials( soil, plants etc) . and also metal composition in alloys can be determined.
Using high sensitive TXRF technique elemental concentrations in tracer levels can be analyzed in water, liquid based samples and biomedical samples.

Low Level Alpha- beta Counting Laboratory 

This laboratory has alpha spectroscopy system and beta spectroscopy system which allow to measure alpha and beta emitting radio-nuclides. The establishment of analytical procedures is underway for alpha and beta spectroscopic analytical service. It is expected to utilize this facility for Gross alpha measurements in water and other similar samples in the beginning and to extend the analysis for other samples. It has initiated the analysis of radionuclide specific alpha emitting radio-nuclide analysis using radiochemical techniques and alpha spectrometry. The environmental radioactivity monitoring programme is being supported by this laboratory too.
