can X-ray generate neutrons when it interact with material ?

Hi,
can X-ray generate neutrons when it interact with material ? if yes ,which material ?
thank you !

Only gamma photons with MeV energy can generate neutrons in a suitable target, e.g. Berryllium.

High-energy X-rays, such as used for therapy, can also produce neutrons:

X-rays used for diagnostic imaging do not.

Traditionally, MeV photons haven't been categorized as x-ray. Now, x-ray is apparently describing the generation method rather than an energy range. In his sense, x-ray can of course generate neutrons.
