Abstract
Although much progress was made by using high purity gemanium detectors for direct measurement of239Pu in man, the improvement of lung spectroscopy sensitivity remains a challenge. Previous work showed that passivated implanted planar silicon detectors could provide an alternative by combining high-energy resolution at room temperature and planar geometry with large detection arrays. This paper reports on the status of this research based on the characterisation of 3×3 cm2 and 6×3 cm2 strip silicon detectors. Furthemore, the possibility to apply such detectors towards other monitoring problems for accidental situations such as the direct measurement of small contaminated surfaces was investigated.
