Timepix detector as a tool for X-ray and gamma dosimetry

Popis výsledku v původním jazyce

We present a concept of using Timepix detector for real-time and simultaneous measurements of various external dosimetry and operational quantities in X-ray/gamma fields with broad range of air kerma rates ranging from natural background levels to the order of Gy.h(-1), including intensive pulsed sources used in medicine. Timepix is a hybrid semiconductor detector of ionizing radiation which can visualize tracks of particles interacting in the semiconductor pixelated sensor bump bonded to the Timepix readout chip. Energy deposited in the individual pixels and properties of these tracks enable us to classify the incident radiation and to assign the correct conversion coefficient between a number of detected events and the desired quantity, e.g. an ambient dose equivalent rate. This paper shows calibration measurements of such dosemeter and discusses its properties.
