Environmental Monitoring and Evaluation of the X-Ray Field Flaw Inspection Workplace in a Factory Building
The surrounding radiation environment of the field flaw detection workplace has been theoretically calculated and monitored on site when an industrial X-ray flaw detector in a factory building is operated during the field flaw detection. The results show that when 5mA tube current and 250 kV tube vo...

The surrounding radiation environment of the field flaw detection workplace has been theoretically calculated and monitored on site when an industrial X-ray flaw detector in a factory building is operated during the field flaw detection.

Additionally, the boundary of the controlled area and the supervised area corresponded to the measured value along the main beam direction belongs to the wall in the east of the workshop.
