Hi everyone :) I have one practical question concerning safety. I work in a small store where we use UV lamp to check banknotes.It has both UV A and UV C light. In the manual it says to use UV C in special cases only, because UV C is dangerous. We use UV A all the time, but i found out that using UV C reaveals security features better. I would like to use UVC to check larger notes (we got fake 200€ recently). However, Im afraid that UVC will damage my eyes. Do you think it is safe to use it like 3-4 times a day for a few seconds? I dont look at the lamp directly, it is hidden in a box and UVC reflects from the paper only. Thank you.
