Answer 1

Radiation is just “moving energy”. Light is a type of radiation. Your camera absorbs that energy and produce an image by counting the energy absorbed, just like a large 2D thermometer.

Radioactive materials emit radiation that has very high energy, and the sensor thinks that very intensive light is hitting it, and thus white spots appear.
