A viewer worries about a cell-tracking agent staying in the body for six months, fearing radiation. The creator explains it's non-toxic and non-radioactive, using fluorescence instead to light up cells for imaging.

You're tracking these cells going through a human body, and you're lighting them up. When you put this stuff in my body, you're saying it normally would last 2 hours, and you're making it last for 6 months? For 6 months, I've got little radiated things in my body? Do I really want that?
I wish maybe he would know our material is non-toxic, non-genotoxic to animal and to human body. Actually, our material will not have radiation. Its imaging system is fluorescence. So after it is inserted, it will emit fluorescence.
So it's a fluorescent signal that's in there.
Yes, fluorescent signal.
But even a fluorescent signal, it gives me a little bit of the creeps going through my body. Do I light up at night?
