Ummm... perhaps a UV-C light meter?
Typically $350 to $1,100. You might want to look into borrowing or
renting such a meter.

It'll embrittle plastic quick if it's really UV-C; a disposable bag turning to
dust would convince me it was shining. Or, you could imagine something with
a slit, telescope mirror, thermopile, and grating, if intensity measurement was
important.

I'd think of something quick-and-dirty before shelling out bucks.
