NIST is developing a new type of chip-based sensor for measuring ionizing radiation doses at very small scales, as part of its NIST on a Chip program. This photonic dosimetry technology uses silicon chips and photonics to create highly accurate, miniaturized sensors that can measure radiation dose with high spatial resolution. These sensors could be used in medical and industrial applications, such as radiation therapy planning, semiconductor processing, and sterilization of medical equipment.
The project aims to address the lack of traceable measurement standards for radiation dose at the microscopic level, which is becoming increasingly important as industries push for more precise radiation delivery. NIST is testing how these photonic devices perform under high radiation doses and is exploring ways to embed them into materials or devices for real-time dose monitoring. While the technology is still under development, early tests show that the sensors can withstand high radiation levels with minimal damage, suggesting they could be viable for future use in a variety of fields.
