[Angbor]

which of the following types of electromagnetic radiation can be used to check metal parts for damage? X-rays, Microwave or infrared radiation?

[Halbarad]

X-rays.

Microwaves and infrared are too well absorbed by metals to be of much use. They simply build up heat or make the electrons crazy. So to speak.

X-rays, from decaying radioactive material, can be very good at detecting tiny flaws in metal parts, especially in welds of metallic pieces.

Among the three Xrays alone can penetrate throgh metal .
