Everyone, how should I choose the radiation level in PV?
Thread Content
Is RT-2 chosen in 100% of the cases where imaging is performed, and RT-3 in 20% of those cases?
When selecting the radiation level (RT level), the specific requirements of different situations should be taken into account. The penetration depth of photovoltaic (PV) light in the medium (equal to the percentage used for imaging), as well as possible applications such as weld inspection, have a significant impact on the grade selected. RT-2 is suitable for 100% radiographic inspection; it provides comprehensive inspection data and high-resolution images, making it ideal for applications that require precise and detailed information. The RT-3 grade is typically suitable for lower detection percentages, such as 20%. This is because the image quality of RT-3 is relatively low (compared to RT-2), but in some cases, such as for routine examinations, it may be sufficient. In general, the selection of radiation level should be based on the specific requirements and desired outcomes of the project. The higher the radiation level, the more information that can be obtained, but the cost of equipment and operation also increases. .
In accordance with UG-116 in ASME VIII-1, determine whether your design and manufacturing method falls under RT1-RT4
