- There is no definite information at present on the fog tolerance of film. The radiation tolerance of film to gamma rays seems to fall somewhere between 1 and 50 roentgens. Although the upper limit of 50 roentgens may be possible, it appears more likely that the range will fall between 1 and 10 roentgens. (W.L.H.)

- Re: How does radiation blacken photographic film? « Reply #2 on: 13/04/2016 22:43:40 ». It is the same mechanism as light sensitivity in silver halides. The necessary energy to trigger the chemical reaction can come from visible light, X-Rays, gamma rays, cosmic rays or even alpha/beta particles. Quote from: Wikipedia.
How radiation affects digital camera - Henri Rantanen

- When the ray is absorbed by the electrons in the censor, they get exited and soon release their excess energy as a flash of light. Unless the radiation is affecting the control and processing circuitry of the camera, anomalies seen on the images are not caused by ionizing radiation. Natural background + DSLR electrical noise
Light and Energy - How Photographic Film Works
- https://electronics.howstuffworks.com/film2.htm
- It is the energy in each photon of light that causes a chemical change to the photographic detectors that are coated on the film. The process whereby electromagnetic energy causes chemical changes to matter is known as photochemistry. By carefully engineering materials, they can be chemically stable until they are exposed to radiation (light).

- Like light waves, radioactive waves can active the AgBr in photographic film, thus exposing it. Furthermore, since some types of radioation can penetrate 'solid' materials for short distances, you don't need to directly expose the film to the radioactive source. However, you don't 'see' anything until the film has been developed.
