Access to nuclear technologies is critical for countries around the world. Besides the use of nuclear technologies for medicine, irradiation of single use medical devices, food pasteurization and phytosanitary treatments constitute the other major application of nuclear technologies. Cobalt-60 is the legacy industrial irradiation technology world. Sri Lanka has two cobalt-60 based panoramic irradiation facilities. One of them is privately owned, while the other is a Sri Lanka Atomic Energy Board (SLAEB) owned and operated cobalt-60 irradiation facility at the Sri Lanka Gamma Centre (SLGC). The facility, which started operating in 2014 was designed to cater to both the food/agricultural products industry and the medical industry. However, the demand for surgical products (~ 99% gloves) has been so heavy that only a small portion of its capacity is available for other applications. Given the increasing costs of cobalt-60 re-loading and other challenges, SLAEB is evaluating the use of alternative technologies such as eBeam technology for the country’s expansion of industrial irradiation capacity for both commercial and to foster R&D. The US National Nuclear Security Administration’s Office of Radiological Security (NNSA-ORS) in collaboration Pacific Northwest National Laboratory (PNNL) with SLAEB and the National Center for Electron Beam Research (NCEBR) at Texas A&M University is currently evaluating eBeam technology to meet Sri Lanka’s export and domestic markets. The on-going study is aimed at identifying the specific applications of the technology in both the industrial and the agricultural sectors and identifying the equipment specifications that would be most appropriate to meet Sri Lanka’s needs.
