- High background levels of radiation damage unprocessed photographic materials, which are typically somewhat sensitive to nonvisible portions of the electromagnetic spectrum. The absorption of radiation by photographic films causes photographic fog.

- 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.)

- 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.

- Answer (1 of 4): The 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 …

- Residual radioactivity, which has accidentally been released on several tests, adversely affects the photographic film used in test data acquisition. The report defines this problem in terms of radiation-caused image degradation, radiation/matter interactions, types of radiation released by accidental venting, and the photographic effects of gamma and x radiation.

- Hazards of Radiation and Photographic Film Living cells can be damaged by radiation when it collides with them. Cancer, for example, can be caused by radiation damaging the DNA of a cell. The higher the radiation dose the bigger the risk of the cells becoming cancerous. If the dose reaches a very high level then the cell will die.

- It is completely inapplicable to radiation absorbed by photographic film. The appropriate unit of measure for this study would be either "rads" or "Grays". It so happens that for x-rays 1 rad is equivalent to 1 rem, but Dr. Groves' apparent misunderstanding of the concepts of absorbed dose is very much out of place in a study purporting to give an expert opinion on radiation exposure.

- Abstract. A clear understanding of the photographic effects of various ionizing radiations is essential for the satisfactory formulation of a film-monitoring program. The use of film for radiation measurements has been well studied by several investigators (3, 4, 5). Barkla and Martyn (1) in 1913 concluded that the photographic effect produced by x-rays of a given …

- It generally requires at least two visble photons to produce a permanent change in a halide crystal (you need to deliver enough energy, in a short enough time, to drive the halogen away from the silver atom) but a single gamma photon will produce several secondary photons and electrons when it interacts with the emulsion, and each of these can impart energy to the …

- Radiation produces spots in the image that are caused by high energy particles hitting the CMOS-sensor. 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.
