摘要： By using a scintillation surveymeter with good calibration performance evaluation for a secondary standard radiation field, and a working standard part obtaining an ambient dose equivalent rate, in cooperation with a portable irradiator, and an irradiator lifter, a laser range finder and a laser locator of a relevant radiation source, in-situ calibration is capable of being performed on fixed, or large-scale, or continuous monitoring type radiation monitors to be calibrated stationed in nuclear power plants, nuclear medical departments, and other nuclear facility operating institutions. Moreover, a time-efficient and effective in-situ calibration method is further provided, which can be performed based upon a standard calibration field that is achieved using a portable 137Cs radiation source. The in-situ calibration method is capable of saving the trouble of delivering large-scale monitors, or monitors difficult to move, or monitors requiring continuous monitoring to calibration laboratories for scheduled calibration.

摘要： A penetration 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 protection 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.
