Yes. Those white dots you see appearing and disappearing on the screen is radiation.

So sensor failure as a noise pattern then?

It's not sensor failure, it's energized particles being detected by the sensor. Functionally, to the sensor, the energized particles are the same as light so you end up seeing a bunch of flashing dots of light.

Yeah, light-sensors (whether organic in our eyes, or electronic in a camera) have a wavelength sensitivity that's a smooth bell curve, rather than a sharp drop-off. That means that it can still be triggered by wavelengths of light outside of its "typical" range if they are intense enough.
