Abstract:
The present invention relates to a method of energy spectrum analysis for sodium iodide (NaI) detector, by which an energy spectrum characteristic obtained from a sodium iodide (NaI) detector is analyzed and used for establishing a system capable of qualitative nuclide identification and activity determination that can be adapted in applications of waste clearance management.
Abstract:
A radioactivity measuring apparatus with a rotating stage for waste drums is provided, which includes a case, a plurality of radioactive counters, a rotation unit, and a control unit. The case has an opening and an accommodating space in communication with the opening. A shielding gate is connected to one side of the opening. The plurality of radioactive counters is disposed in the accommodating space, and used for detecting a radioactive counting associated with a sample. The rotation unit is disposed at a wall on a side of the shielding gate corresponding to the opening, and used for supporting the sample. The control unit is electrically connected to the rotation unit and the plurality of radioactive counters, and used for controlling the rotation unit to rotate by a control signal, so as to enable the sample to rotate within the accommodating space.

Abstract:
An active heat dissipating LED illumination lamp includes a substrate holder, at least one LED illumination assembly, a plurality of heat pipes and a heat sink module. The LED illumination assembly is installed on a side of the substrate holder, and the heat pipes and the heat sink module are installed on the other side of the substrate holder, and a plurality of first diversion channels is formed between the heat pipes, and each heat dissipating fin has at least one ventilation hole occupying 12%˜60% of the total area to form a second diversion channel, and a second interval is defined between the bottom of the heat sink module and the substrate holder. When the heat generated by the LED illumination assembly is provided for performing heat conduction, the heat is guided actively to the second diversion channel to perform heat convection.
