Title:
MEASUREMENT DEVICE FOR AUTOMATICALLY CORRECTING RADIATION DETECTION EFFICIENCY OF SCINTILLATION DETECTOR
Document Type and Number:
WIPO Patent Application WO/2020/029320
Kind Code:
A1
Abstract:
Disclosed is a measurement device for automatically correcting the radiation detection efficiency of a scintillation detector, the measurement device comprising a verification source (2) containing trace long half-life natural radioactivity, a shielding shell (30), a drive device, a connection support (1) and a control panel, wherein the shielding shell (30) is made of a nuclear radiation prevention material, characterized in that the shielding shell (30) covers the verification source (2); the shielding shell (30) is provided with an opening (31) for the radiation of the verification source (2); the drive device is connected to the shielding shell (30); the shielding shell (30) is mounted on a detector via the connection support (1); the control panel is electrically connected to the drive device; the control panel controls the drive device, such that the opening (31) on the shielding shell (30) directly faces or faces away from the detector (4) and is open or closed; the control panel is further connected to a high-voltage circuit and an operational amplifier circuit that are inside the detector (4); and the control panel adjusts gain parameters of the high-voltage circuit and the operational amplifier circuit.
