Much UV leak out do you think?

Fo a go-no go test you might look to see if the UV is strong enough to
illuminate anything with UV writing on it. UK currency notes and
European passports carry invisible (to the eye) markings that light when
lit with even soft UV. My UV lightbox for PCB manufacture and UV leds
are sufficient when held very close. I'm guessing that USA currency
and/or passports might be marked as well? Or else writing using a UV
security marker pen perhaps.
