 Today, I'm going to show you how this small device helps to prevent the spread of nukria weapons. This is a cell, and this, and this, and this. Cells come in all shapes and sizes, and they have been used in different forms for hundreds of years. But do you know that cells are also an important tool in ensuring that nukria material is kept in peaceful use? Worldwide, nukria material is used in a variety of ways, in power plants to produce clean energy, in medical imaging and diagnosis, or cancer treatment to name just a few. And cells are one of the solutions to a basic problem. For example, nukria material can be stored in a container, and when I seal it, I can tell if the container was opened or not when I return later. Nukria inspectors like me have used such cells for more than 50 years, and this year we are introducing a new generation of cells. Here is a glimpse at this tiny new device. And this is how such a small thing makes such a big difference in contributing to international peace and security.
