There are plenty of DIY camera mods out there, but this is the first time we have ever seen anyone create their own radiation detector. Lathrop’s technique involves covering a couple of layers of scintillator in a reflective material, placing them in front of the camera’s lens, and then light sealing it to the best of your ability. Scintillators are materials that when hit by radiation, they luminesce. In other words, when hit by invisible radioactive particles they emit visible light. In this setup they’re the only light source, and manage to show how much radiation is being emitted down to a 100 banana dose.

Lathrop describes his project as:

The big problem is that scintillators aren’t exactly easy to come by. You can use Pyrex, as mentioned above, but it’s notably less efficient. Unless you happen to be working in a lab, the chances of you having any plastic scintillators floating around your workshop is pretty slim.
