Using photographic film to measure radioactivity
- https://physics.stackexchange.com/questions/666173/using-photographic-film-to-measure-radioactivity
- Only a small fraction of gammas would cause ionization within the film. You would need some way to estimate what fraction of the tracks were caused by background or cosmic radiation (perhaps long before you bought the film). You would need some systematic way of counting the tracks using a microscope. Share.

- Photographic film darkens on exposure to ionizing radiation and is an indicator of the presence of radioactivity. Film is often used for determining personnel exposure and making other dose measurements for which a record of dose accumulated over a period of time is necessary, or for which a permanent record is required.

- Photographic film goes darker when it absorbs radiation, just like it does when it absorbs visible light. The more radiation the film absorbs, the darker it is when it is developed.

- Back to Results. The Effect of Radiation on Selected Photographic Film We conducted this film test to evaluate several manufacturers' photographic films for their ability to acquire imagery on the International Space Station. We selected 25 motion picture, photographic slide, and negative films from three different film manufacturers.

- The absorption of radiation by photographic films causes photographic fog. Fog occurs when photographic materials absorb uniform levels of energy that is part of an intended photographic exposure. Fog affects the coarsest portions of the photographic media that comprise the most light-sensitive portions of films.

- Therefore, the photographic industry moust submoit the primoary moaterials to rigorous controls for radioactive contamoination. The principal sources of radioactive residues are atomoic and hydrogen bombs, reactors, and the utilization of radioisotopes. The moeasuremoent of the radioactive contamoination of the atmosphere is moade regularly. (tr-auth)

- Inside there is a piece of film behind some windows (see below). People who work with radioactivity (or X-rays) wear a film badge to monitor their exposure. Radiation will make photographic film darken in the same way that exposure to light and X-rays do. The greater the amount of radiation that the film is exposed to, the darker the film becomes. What is the …
Photographic film - Wikipedia
- https://en.wikipedia.org/wiki/Photographic_film
- Film optimized for detecting X-ray radiation is commonly used for medical radiography and industrial radiography by placing the subject between the film and a source of X-rays or gamma rays, without a lens, as if a translucent object were imaged by being placed between a light source and standard film. Unlike other types of film, X-ray film has a sensitive emulsion on both sides …

- When exposed to ionising radiation, photographic film will turn from being transparent to dark and non-transparent. This effect is used by people who work with radiation in …
