Project history:

  • In 2006, approval was granted for the establishment of a Multipurpose Gamma Irradiator Project under the Ministry of Science and Technology.

  • A 30 acre extent of land at Biyagama belonging to the Board of Investment (BOI) adjoining the Biyagama Export Processing Zone (BEPZ) was selected for the site.

  • Land development contract awarded in 2009 and completed in December 2010.

  • Contract for the supply and installation of Machinery and equipment awarded in 2008.

  • Contract for Civil works awarded in September 2011.

Current stage of implementation (as at 1st March 2013)-

  • Civil works on schedule.

  • Installation of machinery and equipment ongoing.

Expected outcomes of the Project

  • Increase export earnings through value addition to latex gloves produced for export.

  • Establishment of new industries to produce medical products (increased employment in villages)

  • Education in the importation of medical products

  • Improvement in health care

  • Better market for agricultural export products through quality improvement

  • Acceptance of local agriculture products as being free of banned chemicals used for fumigation

  • Reduction of post-harvest losses

  • Improvements in the quality of agricultural products locally consumed (improving food safety and security)

  • Development of innovative products in health care, food packing and agricultural application through R&D using radiation.


A typical Model of a Gamma Irradiation Facility.
The radiation source is fully shield by a thick concrete shell. The thickness of the concrete above ground level is almost 2m. The radiation source is submerged in water in an underground storage pool and is mechanized to be lifted by the source rack. Irradiation occurs when the products are exposed to the radiation source which is lifted above its storage pool.
