Changes in the radiation field can mean an increased risk to workers or sensitive equipment. That is why radiation monitoring and dosimetry are implemented as safety measures in factories and laboratories.
The AdvaDose project is set to create a device with three main functions. It will
- detect changes in the radiation field compared to one or more reference fields,
- spectrally and directionally characterize the radiation field as a whole and in terms of individual particle components and
- capture temporal changes in these characteristics.
The image above shows examples of different clusters – energy generated in each pixel as a result of the interaction with each particle. Their shape and intensity vary depending on the type of particle, its energy, and the angle at which it hits the sensor.
These clusters are key in comparing the reference radiation field with the measured data. Without such comparison, the values measured by dosimetry equipment may be significantly over- or underestimated.
The AdvaDose monitoring device will be based on a single-chip or multi-chip detector configuration with ASIC chips from the hashtagTimepix family combined with software that processes the data measured by the detector into user-friendly outputs.
This project will be funded by the Technology Agency of the Czech Republic’s TREND program. Our partners include the Czech Metrology Institute, NUVIA, and ÚJF AV ČR.
