Direct Ion Storage (DIS) technology plays a crucial role in radiation dosimetry by measuring and recording the exposure to ionizing radiation. It does this by employing a solid-state material that can capture and store radiation-generated charged particles. When radiation interacts with the detector, it releases these charged particles, causing them to move within the material. The movement of these particles creates an electric current, which is then measured to determine the amount of radiation exposure. DIS technology is advantageous in dosimetry because it offers precise and reliable measurements and provides a permanent record of radiation exposure, making it invaluable in any setting for ensuring safe radiation levels.

How Direct Ion Storage (DIS) Technology Works

• Surface of the floating gate is exposed to the surrounding space.
• Ions in the form of electric charge are gathered within the floating gate.
• Source anode has a non-volatile memory cell element.
• Memory cell is surrounded by an ion chamber filled with gas.
• Secondary electrons generated by initial interactions within the chamber wall ionize the gas inside.
• Ions are separated between the electrode and wall, then stored in the memory element cell.
