unbelievable...
I wonder what trick they want to use. Film is easy to make insensitive to infrared and longer wavelengths, but to UV and X-ray and gamma radiation it is not, since the energy of these radiations is higher than visible light. Unless they base it on some kind of semiconductor...🙂
OTOH, maybe they will reintroduce TechPan - that is pretty insensitive to x-ray, just like to any other electromagnetic radiation🙂
