The difference between X-ray and gamma rays in non-destructive testing equipment

Non destructive testing equipment uses X-ray for penetration testing operations, which is different from gamma rays. Essentially, both belong to radiation, but there are differences in strength, as follows:

Gamma rays are a type of strong electromagnetic wave, with a wavelength shorter than X-rays, generally not exceeding 0.001nm, and their frequency is high, so they have a very strong penetrating power. Experimental tests have shown that gamma rays can penetrate brick walls up to 1 meter thick;

X-rays are also a type of strong electromagnetic wave, but their penetration is not as strong as gamma rays, with the main difference being:

1. X-rays are products of bremsstrahlung, while gamma rays are products of isotopic nuclear fission;

The energy of X-rays depends on the voltage of the discharge tube, while the energy of gamma rays depends on the type of isotope;

3. X-rays are controllable, while gamma rays are uncontrollable;

Whether to use X-rays or gamma rays for detection equipment depends on the actual situation. As mentioned above, X-rays are controllable light that can be adjusted according to actual needs, with high flexibility. However, gamma rays are uncontrollable and have weak sensitivity, so they are generally not used in conventional applications to avoid personnel injury caused by radiation leakage.
