Near a nuclear reactor or a fuel container, mixed neutron/gamma fields are very common, necessitating routine neutron dosimetry. Accurate neutron dosimetry is complicated by the fact that the neutron effective dose is strongly dependent on the neutron energy and the direction distribution of the neutron fluence. Neutron field characterisation is indispensable if one wants to obtain a reliable estimate for the neutron dose. A measurement campaign at CANDU nuclear power plant located in Cernavoda, Romania, was set up to characterise the neutron fields in four different locations and to investigate the behaviour of different neutron personal dosemeters. This investigation intends to assist in choosing a suitable neutron dosimetry system at this nuclear power plant.
在核反应堆或燃料容器附近，中子/伽马混合场非常常见，因此需要进行常规中子剂量测定。准确的中子剂量测定很复杂，因为中子有效剂量强烈依赖于中子能量和中子注量的方向分布。如果要获得可靠的中子剂量估计值，中子场表征是必不可少的。在罗马尼亚切尔纳沃德的坎杜核电站开展了一项测量活动，以表征四个不同位置的中子场，并研究不同中子个人剂量计的性能。这项调查旨在协助该核电站选择合适的中子剂量测定系统。
