    Doses as low as Gy have been reported to cause problems, though other reports have demonstrated safe operation up to Gy, indicating the unpredictable and random nature of device failure. 2, For instance, in one study, four patients with a proton dose range of Gy and neutron dose of Sv developed CIED resets. 64 The. dosimetry or radiotherapy technology. The intent of the text is to serve as a factual supplement to the various textbooks on medical physics and to provide basic radiation oncology physics knowledge in the form of a syllabus covering all modern aspects of radiation oncology physics. While the text is mainly aimed at radiation oncology.

    The BD-PND is the recommended detector for personal neutron dosimetry. Its sensitivity exceeds the ICRP requirements for neutron dosimetry. It incorporates automatic compensation for sensitivity change with temperature over the operational range of 20 - 37 °C.
