Radiation dosimeter reading unit for space applications

Summaray of project:

Measuring radiation dose and dose rate is a common task in the space radiation environment. This is achieved using specialized instruments known as radiation dosimeters. This is not only limited to use in space, but is most commonly used in radiation therapy

And in nuclear stations. The most common technologies used in radiation dosimeters are photodiodes, MOS transistors, and radiation-sensitive field-effect transistors. RADFETs The functional requirements for space radiation measuring instruments vary depending on whether they provide integrated data (e.g., “non-powered” detectors) or time-resolved information (“active, e.g., powered, detectors”), and whether the data is used to characterize the radiation environment (area measurements) or an individual dose. In this project, we propose a design concept for a radiation reading system for real-time measurement of absorbed dose and dose rate. The developed circuits are in principle applicable also outside the field of pure scientific research, for applications In nuclear devices, medical imaging, security and industrial scanners, and others.
