[ RadSafe ] Security and background check for radioactive material users

[Jean-Francois, Stephane]

Good morning,

A couple of years ago I have heard from unofficial sources that USNRC
was thinking about a security or background check for authorized users
of large sealed sources (irradiators for example).

Is this true  ?  And if so, is it currently in application in the US ?
What is required ?

Would you know any other place in the world where this might be applied
for sealed sources users ?

Thanks in advance.
