A groundbreaking mobile application, the Personal Alarm Assessment Tool (PAAT), has been developed through a collaboration between the International Atomic Energy Agency (IAEA) and the Department of Physics, University of Sri Jayewardenepura. This innovative app is designed to enhance the safety of front-line officers at key entry points such as airports, border crossings, and major public events. PAAT allows officers to swiftly assess alarms triggered by radiation detection systems, enabling faster and more efficient responses to potential threats. Now available for public use, the app represents a significant advancement in global radiation safety.

The Department of Physics at USJ played a crucial role in this project. Under the leadership of Prof. N. G. S. Shantha Gamage, the team comprised Dr. W. Wasanthi P. De Silva, Prof. W. K. I. L. Wanniarachchi, and Mr. B. H. Lakshitha M. Fernando. They were instrumental in simulating radiation data using advanced Fluka software. Computation facilities for these simulations were provided by Tohoku University, Japan. The simulated data was validated against experimental results obtained from Apeksha Hospital, Maharagama, using instruments supplied by the Sri Lanka Atomic Energy Board, ensuring the app’s accuracy and reliability in real-world scenarios. The project was supported by a grant from the IAEA awarded to Prof. Shantha Gamage, Department of Physics, University of Sri Jayewardenepura. The development of PAAT was funded by the IAEA, headquartered in Vienna, Austria. The project was coordinated by Dr. Nadeera Gunaratna, currently a consultant at the IAEA.
PAAT brings significant advantages to both security personnel and the general public by providing a tool that accurately assesses radiation risks in a timely manner. This collaboration between Sri Lankan physicists and the IAEA underscores the international importance of this achievement and highlights Sri Lanka’s contributions to global safety technology. This marks a monumental advancement in radiation detection technology, and the team behind its development deserves recognition for their expertise and dedication.
On November 11th and 12th, 2024, the Department of Physics, in partnership with the Staff Development Centre at the University of Sri Jayewardenepura, held an intensive workshop titled “Mastering Technical Leadership and Career Growth: Skills Beyond the Toolbox”. The event took place at the Department of Physics and was aimed at Technical Officers from the Faculties of Applied Sciences, Technology, and Engineering. The workshop offered essential training to advance participants’ careers and prepare them for leadership roles.
The workshop was organized and overseen by Prof. Shantha Gamage, Head of the Department of Physics. Dr. Shivaini Kandeepan, the Workshop Coordinator, played a key role in ensuring the program’s smooth execution, contributing significantly to the event’s success. The initiative was launched by Prof. Upul Subasinghe, Dean of the Faculty of Applied Sciences, who recognized the need for skills development beyond traditional technical training of the Technical officers of the Faculty of Applied Sciences. Prof. Saman Yapa, Director of the Staff Development Centre, provided crucial financial support for the program.
The two-day workshop was structured into four sessions, with participants divided into groups that rotated through each session over both days. This format ensured that all attendees had ample time to explore each topic, engage in hands-on activities, and interact closely with instructors. The sessions were designed to equip Technical Officers with the skills needed to assume leadership roles in their respective fields. Topics included: Lab Safety and Equipment Inventory Maintenance, Fundamental Measuring Instruments in Physics and Engineering; Principles, Uses, and Accuracy, Fundamentals of Electronics; House Wiring, Solar Panel Installation; and Workshop Training
The workshop began with an introductory lecture by Dr. Manuranga Fernando on multimeters, which laid a solid foundation for the following sessions. Dr. Fernando’s lecture introduced participants to the fundamental operation and various uses of multimeters, a key instrument for measuring electrical values. This knowledge is crucial for accurate measurements and troubleshooting in technical and engineering environments, establishing a solid base for hands-on training.
The first session provided a detailed overview of key instruments used in educational and research settings. Prof. Lilani Attygalle and Dr. W.G.C. Wijayasundara delivered an insightful lecture on Measuring Instruments and Instrument Maintenance.
