AW: [ RadSafe ] NRC Says Indian Point, Other Radioactive Leaks Led to Mistrust

[Rainer.Facius at dlr.de]

Stewart,
 
which nuclear reactions with stable nuclei can be triggered by 20 MeV electrons creating thereby radioactive, i.e. unstable nuclei?
 
Rainer

Hi all,
Before dismissing the quote out of hand, bear in mind we really don't know
for sure what is being referrred to.

If by "x-ray equipment" the article is making reference to a linear
accelerator [linac] used in radiation oncology [and not just a simple x-ray
unit used for diagnostic purposes], these linac units can put out a steady
beam of photons in multiple energies of from 6MV to 18MV or more [as well as
electrons in multiple energies up to 20 MeV or more]. Linacs can be used to
irradiate target materials which can make radioactive isotopes which could
theoretically be used for illicit purposes.  Just a thought which should be
recognized.

Hospitals and therapy centers often upgrade their installed linacs and the
older units are deinstalled and sold in the US and abroad.
