In the present work, preliminary observations have been performed in order to apply a direct CCD read-out technique to the self-activation method with a CsI scintillator plate using a Pu-Be source and a 10-MV linac. In conclusion, it has been revealed that the CCD read-out technique is applicable to neutron measurement around a high-energy X-ray radiotherapy machine with the self-activation of a CsI plate. Such application may provide a possibility of novel method for simple neutron dose-distribution measurement.}, pages = {21--23}, title = {An application of CCD read-out technique to neutron distribution measurement using the self-activation method with a CsI scintillator plate}, volume = {832}, year = {2016} }
