Questions regarding non-destructive testing
Thread Content
Today I wrote a sentence: “Use X-rays instead of gamma rays for non-destructive testing.” Experts say this is incorrect; alpha rays, beta rays, and gamma rays are all types of X-rays, and it should be specified whether it is alpha or beta that replaces gamma. Are they scammers? I’m a complete beginner; please advise, experts.
Personally, I think what the “expert” said is incorrect.
Differences between X-rays and gamma rays: different sources, different wavelengths, different frequencies, different penetration capabilities, different uses
X-rays, also known as Röntgen rays, are what people usually refer to as X-rays. Their wavelength lies between that of ultraviolet rays and gamma rays; they can penetrate materials that are opaque to visible light. Non-destructive testing makes use of this property :)
