The 3M Empore RAD Disk is thin and only 47 millimeters in diameter. It is composed of very small sorbent particles that are held together within a matrix of polytetrafluoroethylene, or PTFE. The disks act as a filtration and separation system, selectively separating and retaining dissolved substances to be analyzed.

To help researchers in the field measure radio-cesium levels in a more rapid and simplified way, Hiroaki and his team developed a special 'RAD Disk Pack,' which consists of three pre-filters and the 3M Empore RAD Disk-Cesium. The team also created pressure filtration equipment called the 'RAD Disk Sampler,' which helped speed up processing time.

When the two systems are used together, researchers are able to separate and condense radio-cesium in water into dissolved and turbid components more easily. This allows them to measure overall radio-cesium levels faster than the traditional separation method.
