That's not what's claimed.
What's claimed is that shooting electrons at the screen fast enough
both (a) generated X-rays, and (b) rendered that screen radioactive.
This has nothing to do with whether X-rays can make what they hit
radioactive.
Anyway, if an electron beam can cause something to be radioactive, then
X-rays can too, by using the photoelectric effect to generate an
electron beam within the material, no?

I had a GE theatre size projector which had an
integrated CRT. It
used such high voltage to zap phosphor that it was an Xray hazzard,
and in and of itself had become radioactive from long operation
As has been said
here before, it is NOT possible to make things
become radioactive from shooting x-rays at them.
