Automatic verification device for surface pollute
The radioactive surface pollution monitor is equipped in the hospital's nuclear medicine, health and epidemic prevention and environmental protection departments. As an important radioactive measuring instrument, the surface pollution meter and the radioactivity meter all belong to the compulsory verification measurement instruments. The device can meet the requirements of the metrological verification regulation JJG478-96 "alpha, beta and gamma surface pollute". As the plane source of the main standard device, it must have the accuracy and uniformity of the quantity, the area of the active area is larger than the detection area of the detected instrument, and the Alpha and Beta sources must be equipped with a complete activity series to meet the requirements. Verification requirements for key technical indicators such as linearity, basic error and other instruments. At the same time, our company has developed an automatic verification device, which can be controlled by software to realize the automatic selection of the plane source. Through the program control, the plane source is automatically placed in the calibrating position to avoid the disadvantages of the inspectors' direct operation of the radioactive source. It has realized the safety and reliability of the verification work.
