Photodiodes for Radon Detection

The Excelitas VTH21 Series of photodiodes are offered in chip form for optimal alpha particle detection such as radon gas detection applications. Featuring a robust chip design, these low capacitance silicon photodiodes provide high responsivity to radiation of interest. These photodiodes are available in both a 5x5mm and 10x10 mm large active area for maximum detection of low level radiation and a spectral response between 400 nm and 1100 nm.
