Abstract :
A portable microdosimeter has been designed, covering a dynamic range of 120 dB in a single signal processing channel. A transistor is employed as non-linear element and deviation at low and high energies from a truly logarithmic characteristic is corrected by a microcomputer. A description of the basic design and experimental result are given.
