It's part of this Analog Horror video by Gooseworx: https://www.youtube.com/watch?v=Td2x8s9GZlo
A thorough explanation for those who don't want to watch
It's a video of two different fake commercials for fictional drugs called Thalasin and Thalasin Plus. While the former is ostensibly for emotional regulation, the latter supposedly allows the taker to experience increasingly strange and alien 'emotions'. Over the course of the video, a human face is used to emphasize these emotions, both normal and strange, though the faces with Thalasin Plus slowly grow more and more twisted and painful.
It's worth a watch if you can take analog horror.
A rod of Cobalt-60, a highly radioactive isotope. There's a reason it says on the side "Drop & run". Its radioactivity is the reason it's messing up the photo- as the energetic radiation strikes the cells in the phone camera, it causes those cells to light up.
