The response of charge coupled devices (CCDs) to α radiation has been investigated to assess the potential of using these devices to perform α-particle detection and measurement. Previous research indicates that α radiation leaves distinctive patterns in the images produced by CCDs when compared with other types of radiation. In this research, CCD responses to α and β radiation have been compared to highlight these differences. The CCD used was a Sony ICX825AL interline transfer CCD with an 9.98 × 6.71 mm imaging area consisting of 1392 × 1040 pixels, each of size 6.45 × 6.45 μm, covered with a thin aluminised Mylar film to stop exposure to light. Images have been taken of exposures to a 210Po source and horizontal streaks have been observed. It is thought the horizontal streaks are caused by the charge produced by the α particles being read out over several cycles. The average length of the streaks was found to be 14.5 ± 2.0 pixels. Future research will be done to further assess streaks produced by different energy α particles to investigate the potential of using CCDs for spectroscopy, using the MC40 cyclotron at the University of Birmingham.
