Introduction: Microdosimetry is a fundamental method that studies the nature of energy transfer in micron volumes in the particular biological cells. In a biological target, the amount of ionization does not indicate the magnitude of biological radiation-induced damage. However, the severity of biological harm depends strongly on the amount of the linear energy transfer along t...
Fast nuclei are ionizing radiation which can cause deleterious effects to irradiated cells. The modelling of the interactions of such ions with matter and the related effects are very important to physics, radiobiology, medicine and space science and technology. A powerful method to study the interactions of ionizing radiation with biological systems was developed in the field of microdosimetry...
The development of microdosimeters and particle telescopes is important for risk assessment in space and aviation applications. The charge collection properties of a monolithic particle telescope, suitable for both microdosimetry and fluence based approaches, were studied using an ion microprobe.
Solid-state silicon detectors are challenging devices for microdosimetry, mainly because they can provide sensitive zones (i.e. depletion layers) of the order of a micrometer. This type of detector can be realized by placing a tissueequivalent converter in contact with a silicon device. A semiconductor microdosimeter is characterized by a high spatial and a good energy resolution and could be u...
In microdosimetry, lineal energies y are calculated from energy depositions ? inside the microdosimeter divided by mean chord length , whose value is based on geometrical assumptions both detector and radiation field. This work presents an innovative two-stages hybrid (HDM: for microdosimetry) composed a tissue equivalent proportional counter silicon tracker made of 4 low gain avalanche diode. ...
