Abstract
The work is aimed at developing an in vivo spectroscopy system for rad iation protection monitoring to improve the lung detection of Pu-239 a nd Am-241. Silicon components have been investigated for high-resoluti on spectroscopy (2 keV) at room temperature to measure 59.5 keV Am-241 gamma rays. The requirements and constraints of such device are revie wed. The work is focused on analog electronics and detector developmen t. As a first step, multi-channel electronic circuits based on a low-n oise charge-sensitive preamplifier have been built by carrying the FET s and feedback capacitances close to the strips. The performance is pr esented for a large-area strip silicon detector (3 x 3 cm(2)). Measure ments are compared with simulations and discussed with respect to appl ication requirements.
