Center of Plasma Physics-Institute for Plasma Research, Nazirakhat, Assam, has the neutron source based on Inertial Electrostatic Confinement of Fusion. In order to scale up the source, it is planned to build a neutron source facility. The facility needs the construction approval from AERB India for occupational radiation safety during the operation and after the operation. It will also assess the short-term and long-term radiological hazards due to the neutron source. In order to evaluate the post irradiation radiation hazards due the neutron source, the radioactivation analysis of laboratory is carried out and reported here. The radioactivity in the laboratory building and source components after short-term and long-term operation has been assessed. The tritium activity in the soil is also evaluated. The calculation is also done for the contact dose rate estimations after operation to assess the maintenance applicability inside the laboratory. The inhalation dose inside the laboratory after the operation has been also calculated to avoid any hazards after operation maintenance activities. The article provides the complete details of post operation hazards analysis for the Inertial Electrostatic Confinement Fusion neutron source facility.
