Instax Film and Airport X-Rays: Risks and Tips 2026

Instax Film and Airport X-Rays: Fact vs Fiction

Heading off on holiday with your Instax or Polaroid is second nature for many travellers — and it's also one of the questions that comes up most often: does the security scanner damage film? Short answer: it depends on the scanner, and the risk increases with the newer machines. Here's what Fujifilm and Polaroid actually say, and how to travel without nasty surprises.

Why X-rays damage undeveloped film

Undeveloped instant film is a chemical emulsion waiting to be exposed to light. X-rays pass through the packaging and the cartridge, and can expose the film "early" in a diffuse way. In practical terms, on your photos that means:

• an overall fog (hazy image, blacks turning smoky grey);
• irregular light streaks or bands;
• a loss of detail in dark areas.

Two aggravating factors:

1. Film speed. Instax films are fast emulsions (ISO 800); Polaroid i-Type/600 sit around ISO 640. The more sensitive a film is, the more it reacts to radiation.
2. The cumulative effect. Every pass through a scanner adds its dose. A return trip with a connection can mean 3 or 4 scans — and fog that adds up.

The good news: already-developed photos are not at risk. Once the chemistry is set, radiation has no further effect.

Old scanners vs CT scanners: the difference that matters

"Classic" X-rays

Traditional carry-on X-ray scanners use a relatively low dose. For a moderately sensitive film, a single pass often leaves little or no visible trace. That's why so many travellers have put their film through scanners for years without ever noticing anything. But "often" is not "always", and every additional pass increases the exposure.

CT scanners (computed tomography)

Since 2020, new CT scanners — the same technology as medical CT scanners — have been rolling out in airports, first in the United States and then gradually elsewhere. These machines scan luggage from multiple angles at higher doses.

Fujifilm has issued an official warning: these new scanners "can be more damaging to undeveloped film and Instax film than previous generations." For its part, Kodak tested a Portra 400 film in a CT scanner at JFK airport with the TSA: significant fog from a single pass, with "smoky" blacks and a loss of shadow detail. Kodak recommends never putting undeveloped film — exposed or not — through a CT scanner.

The problem: from the outside, it's hard to tell a CT scanner from an older model. Hence the golden rule below.

The 5 rules for travelling with film

1. Always in carry-on, never in checked luggage

Checked-baggage scanners are significantly more powerful than cabin ones. Film in the hold is very likely to be fogged, even in its original packaging. Film and your loaded camera travel with you, in the cabin.

2. Request a hand inspection

This is Fujifilm's official recommendation for Instax film. The method:

• Take the cartridges out of your bag and place them in a clear bag, easy to present.
• Before putting your belongings on the belt, tell the officer you're carrying undeveloped photographic film and ask for a manual check.
• Unload the camera before the checkpoint if possible: a cartridge already loaded in the camera will have to follow the same path anyway, so you might as well have it inspected with the others.

In the United States, the TSA explicitly provides for hand inspection on request. In Europe, the practice varies by airport, but a polite request with well-presented film is most often accepted.

3. Limit the number of scans

If a hand inspection is refused, group all your film in a single bag to avoid multiple scans, and use first the film that has already been through a scanner.

4. Buy on site (or get it delivered to your destination)

The zero-risk solution: travel light and buy your film on arrival. Instax Mini film is available in most tourist destinations — just check the expiry date and in-store storage conditions (see our guide to spotting expired film). Another option: order online with delivery to your accommodation.

5. Don't rely on "X-ray-proof" pouches

The lead-lined pouches sold to protect film have a perverse effect: the scanner automatically increases its dose to see through them, which can make the fogging worse instead of preventing it — or lead to a manual search anyway. Asking for a hand inspection directly remains the clean route.

What about Polaroid film?

Same logic. Polaroid camera and film makers recommend the same approach: cabin rather than hold, hand inspection, and limiting the number of scans. Already-developed photos are perfectly safe. If you're hesitating between bringing your stock or buying more on site, our complete guide to Polaroid film will help you estimate how much you'll actually use during the trip.

In a nutshell

• Undeveloped Instax or Polaroid film is sensitive to X-rays: fog, streaks, loss of detail.
• The new CT scanners are harsher than the old ones — a single pass can be enough, according to Kodak/TSA tests.
• Carry-on only — never put undeveloped film in checked luggage.
• Hand inspection: ask politely, film presented in a clear bag.
• Reliable plan B: buy film at your destination.
