摘要： 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.

摘要： A water phantom structure with fixed water level for measuring dose of ionizing radiation absorbed to water and the method thereof are disclosed, in which the water phantom structure comprises: a tank, enclosed by four wall plates and a bottom plates, all made of an isohydric material, and having 95% of its volume to be filled with a water solution; a concave lid, being a plate configured with a fillister and made of an isohydric material to be placed in the tank while floating on the water solution for settling the water level of the water solution from undulating and thus capable of acting as a reference water level; and a moving device. The aforesaid water phantom structure can be applied in operations for measuring or calibrating output radiation doses emitted from devices such as medical gamma-ray radiation devices or linear accelerators, using which the measurement will not be interfered by the undulation of water level commonly seen in those conventional water phantom since the aforesaid water phantom structure is able to provide a fixed water level by suppressing such undulation with the concave lid.
