Silicon based 3D mini- and microdosimeter (3DMiMic) (completed)

Exposure to radiation is generally hazardous to human health while proved to be extremely successful in the treatment of cancer and tumours. In both cases, it is paramount to predict the associated risk caused by the radiation and to understand the radiobiological properties of the radiation absorbed by our tissues using radiation protection and detection.

About the project

This project addresses the aspects in radiation dosimetry through the development of advanced semiconductor radiation detectors and related instrumentation that are specific for terrestrial and space radiation protection and for quality assurance in radiation therapy.

3D silicon based radiation technology using advanced microelectronic and nanotechnology will develop new silicon sensors in microdosimetry. These sensors will mimic the response to ionizing radiation on a cellular and sub-cellular level of biological tissues, providing an aid to predict the outcomes of contemporary hadron radiation therapy and the risk associated with radiation in terrestrial and space environments.

The results of the project establishes a knowledge platform for the use of 3D radiation detector technology in advanced radiation dosimetry to develop a suite of instrumentation that will improve the quality of life in cancer patients and in individuals who are living with radiation hazards. The project is multi-disciplinary, supported by a strong international collaboration of leading institutions in the field of microelectronics, radiation detection and dosimetry, radiation oncology and advanced radiation facilities.


The primary objective is to establish a knowledge platform of in-depththeoretical understanding of 3D mini- and microdosimeter through modelling and scientific experiments.

Secondary objectives:

  • To obtain a theoretical knowledge platform of 3D diode as mini- and microdosimeter.
  • To verify the potential improved ability of 3D microdosimeter to measure stochastic energy deposition on a micrometre scale.
  • To perform experimental characterisation of 3D mini- and microdosimeter using state-of-the-art synchrotron radiation facility and ion beam induced current imaging facility.
  • To verify the possibility to fabricate state-of-the-art 3D mini- and microdosimeters in the NorfFab facilities.
