AbstractAbstract
[en] In this work a specific methodology for the evaluation of the conservation status of the internal channel of 192Ir radiators used in industrial scintigraphy in the country, using an industrial videoscope was developed. Wear and damage to the material of the inner channel of the radiators, such as corrosion, erosion or other, can cause obstruction in the channel. Such blockages can result in the source releasing of the remote control, creating accidental overexposure for the team. Therefore, early detection of obstructions in the inner channel of the radiators can prevent occupational accidents. The videoscope is a device that allows the visualization of the conservation status of the inner channel of the radiators. After videoscopic analyses, it was observed that some 192Ir radiators presented wear on the inner channel. Also, we analyzed the equipment of 75Se, because they are more modern and new. Internal channels of selenium radiators are in good condition
