Abstract: An ionization chamber includes a chamber, two outer electrode plates and a center electrode plate. The center electrode plate is disposed at the center of the chamber, and signals produced in the chamber can be collected completely by the center electrode plate to avoid signal losses and improve the accuracy of the test result of the ionization chamber. The center electrode plate also can maintain a constant internal volume of the chamber and prevent a change of effective volume within the chamber due to a change of electric field and enhance the stability of the test result of the ionization chamber. A guard electrode is wrapped by an insulation pin of the electrode and the outer insulation ring to form an insulation shield that can greatly reduce current leakage of the protection electrode and improve the accuracy of the test result of the ionization chamber.

Abstract: A system for analyzing/inspecting airborne radioactive particles sampled in a draft flue is disclosed, which comprises: a front detector, at least an air intake tube, a capture vessel, an inspection device, a flow meter, a hand-held electric device, a blower motor, With the aforesaid system, the radioactivity distribution relating to the airborne particles as well as the peak of the distribution can be detected, by which a sampling time can be determined for achieving longer period of time allowed for an analysis to be performed while rejecting the radioactive interference in the draft flue. Thereby, background noise relating to ambient radioactivity can be minimized and thus the detection limit of the aforesaid system is reduced, so that the system of the invention is much more sensitive compared to those conventional real-time radioactivity detection means with regard to the detection of radioactive nuclides in airborne particles.

Abstract: An environmental survey robot suitable for wireless communicating with a survey action management center having a geographic information system to scheme an advance route with multiple check points is provided. The environmental survey robot includes a moving vehicle, a controlling computer, a wireless communication network, a Global positioning system, an environment detector, a solar cell and a power controller. The wireless communication network receives the advance route from the detecting action management center, and the controlling computer autonomously controls the moving vehicle to move in accordance with the advance route. The environmental detector is suitable for detecting the environment information and sending the same to the controlling computer. When the electricity of the solar cell is less than a predetermined value, the power controller will send the signal to the controlling computer such that the action controller will stop the action of the moving vehicle.
