Three: The harm of X-ray to film
The influence of X-ray machines on film is not completely absent. The difference is only in the size of the influence.
The X-ray machine may have the following effects on your undeveloped film: Partial or overall exposure to varying degrees produces strange streaks or color blocks(1/4 to 3/8 inch(1 to 1.5 cm)Striped pattern with blurred edges.It is not necessarily red, which is similar to light leakage, but may also be yellow and purple. The particles become coarse and so on.![]()
X-ray detection can cause fogging of film negatives. This fogging will weaken the peak of the sensitometric curve, and the dark details will be lost when the image is scanned.
Fog performance:
- Black and white negatives – dark areas.
- Color negatives – dark areas, brown or gray.
- Color reversal film(Slideshow) -Low density area(Light spot).
- Strong X-ray exposure will affect the entire roll of film. The photo appears to be overexposed, grainy, and dark or black images appear green.
The unexposed film will accumulate under the influence of the X-ray machine, and it may not be visible after one or two times, and it may come out if it is too much. There are pictures and texts in the following technical articles. If you are interested, you can learn more about the case.

FilmGuard Bags: protect you film from X-rays
FilmGuard Bags, from Domke, protect your undeveloped film from the streaking and fogging caused by exposure to x-rays during airport security and customs checks. If you&39;re a professional photographer--or a traveler taking snapshots-- you don& ;39;t have to worry about ruining your supply of film.
Available in large and small sizes, FilmGuard protects unprocessed sheet film and cassette film against the low-dosage x-ray machines that are used to check carry-on luggage at airports around the world. With their full-length hook and loop closures, FilmGuard bags also protect your film and disks from dust and weather. FilmGuard is not intended for use in checked luggage, which is exposed to much higher doses of x-rays. So it&39;s always a good idea to first store film in FilmGuard bags and then pack them in your carry-on luggage, rather than checked luggage.
FilmGuard has a rugged, three-layer construction, starting with an outer shell of water-resistant ballistic nylon. In the middle, a lead-impregnated vinyl sheet provides x-ray protection. The interior is lined with smooth, 420 Denier nylon packcloth. When not in use, FilmGuard bags can be stored flat or used as a protective wrap around equipment.
Tested by the experts
FilmGuard bags were tested for effectiveness by InVision Technologies, Inc., manufacturers of the only Federal Aviation Administration-approved checked-luggage scanning system. Films with up to ISO 800 speeds were tested. The extensive tests showed that the FilmGuard design will protect film and disks from the low-dosage x-ray units used to check carry-on luggage. (The tests also showed that the amount of lead needed to protect film from high-dosage x-ray units would make the bags too heavy to be practical. )
