One of the most urgent applications of the irradiator is in the fight to save Jamaica’s world-renowned Blue Mountain coffee. Since 2012, coffee leaf rust has posed a serious threat to the crop, with about one-third of the country’s Arabica coffee plants affected. Using gamma irradiation, ICENS scientists are supporting a mutation breeding programme designed to produce plants with greater resistance to pests and disease. This process introduces beneficial genetic variations naturally, without genetic engineering, and offers the possibility of restoring yields and preserving the economic value of this flagship export.

The benefits of the irradiator will not be limited to coffee alone. ICENS is already applying the technology to crops such as ginger, yam, and sweet potato—staples that are vital for both food security and trade. Gamma irradiation provides a safe way to control spoilage, pests, and pathogens without altering the taste or aroma of these foods, while also extending their shelf life. These improvements could open new opportunities for Jamaica’s agricultural exports, ensuring products meet international quality standards.

Looking ahead, the irradiator is also expected to play a role in public health and medical research. ICENS has begun exploring collaborations with the University Hospital of the West Indies on projects such as sterilizing medical equipment and supporting advances in skin graft technology. In parallel, the machine will assist Jamaica in adopting the Sterile Insect Technique to suppress populations of disease-carrying mosquitoes and agricultural pests, reducing the spread of illnesses and protecting farm yields.

The arrival of the irradiator was preceded by years of preparation, including specialized training for Jamaican scientists in plant tissue culture, molecular screening, and irradiation techniques. Partnerships with the IAEA supported workshops and research fellowships abroad, ensuring the local capacity to use the technology safely and effectively. Jamaica has also strengthened its regulatory framework through the Nuclear Safety and Radiation Protection Act of 2015 and the establishment of the Hazardous Substances Regulatory Authority in 2020, laying the foundation for safe and responsible use of nuclear technology.

For ICENS and the Faculty of Science and Technology, this development marks a major step forward in applying advanced science to national challenges. For Jamaica, the prospects are equally significant: improved crop yields, stronger export potential, enhanced food security, and innovative public health solutions. The gamma irradiator represents not only a scientific achievement but also a symbol of the country’s ability to use cutting-edge research for the benefit of its people and economy.
