What You'll Learn
Ask for a hand check
Asking for a hand check is a common way to avoid putting film through an X-ray scanner at the airport. While some people have reported that their film has been fine after going through an X-ray, others have noticed a loss in contrast and light leaks. As such, it is recommended to ask for a hand check when travelling with film.
When asking for a hand check, it is important to be polite and respectful to the TSA agents. They are there to help you and keep everyone safe. Simply explain that you are travelling with film and ask if they can be hand-checked instead of going through the X-ray machine. Most agents will be accommodating, but it is always good to be prepared for any outcome.
It is also a good idea to have your film easily accessible. This will make the hand check process quicker and easier for everyone involved. You can also put your film in a clear plastic bag, which will make it easier for the agents to inspect. Depending on the agent and the airport, they may just look at the film, or they may swab each individual roll or the plastic bag. Some people have reported that JFK airport tends to swab every single roll, while LAX has been known to be less accommodating.
Keep in mind that not all airports or agents will allow hand checks. In some cases, they may try to scan your film at a higher setting or make you take it out of your bag. If you are concerned about the potential impact on your film, you can always get it developed before you travel or send it to a lab via international shipping. Additionally, be prepared for a potential wait, as hand checks may take longer, especially if the agents are busy or forget about your request.

Conceal items in a way that blends with the body
While it is highly challenging and illegal to mask objects from detection by modern X-ray machines, there are a few methods that can be used to increase your chances of success. Firstly, it is important to understand that X-ray machines detect items based on their density and composition. Therefore, one strategy is to use low-density materials like plastics, glass, or certain ceramics, which absorb fewer X-rays and can sometimes appear less prominently in scans. However, security professionals are trained to recognize the shape and presence of such low-density objects, and advanced X-ray technology can enhance images to reveal these items.
Another approach is to encase the prohibited item within an everyday object or organic material such as food or clothing. Organic materials absorb X-rays differently than inorganic ones, allowing the prohibited item to blend into the background. However, this method may not always be effective as security scanners can differentiate between organic and inorganic materials. Additionally, be cautious when using shielding materials like lead or barium to wrap prohibited items as this can be a red flag for security personnel, leading to further inspections.
Disguising the prohibited item as something else is another option, but it is risky since it's challenging to predict if the object will show up as expected in the X-ray scan. For instance, attempting to conceal gold or electronic devices is often futile as they are easily detectable. On the other hand, small items like a Swiss Army knife might be easier to hide, such as by placing it under your iPhone in your bag, but this is not guaranteed.
Ultimately, while these techniques may provide a chance of success, modern security measures and technologies make it exceedingly difficult to completely mask prohibited items from detection in X-ray scans. The potential legal and ethical consequences of such actions should also be carefully considered.

Hide items in X-ray-sensitive equipment
Hiding items in X-ray-sensitive equipment is not recommended, as it is illegal and unethical, and modern X-ray machines are extremely difficult to trick. However, if you have privacy concerns or legitimate reasons for protecting sensitive information, you should discuss these concerns with security personnel in advance.
That being said, here are some ways to potentially hide items in X-ray-sensitive equipment:
- Use low-density materials: Objects made from low-density materials like plastics, glass, or certain ceramics can appear less prominently on X-ray scans. This is because they absorb fewer X-rays compared to metals. However, security professionals are trained to recognize the shape and presence of such objects, and modern X-ray machines can enhance images to reveal them.
- Shielding materials: Wrapping an object in a thin layer of shielding materials like lead or barium can block X-rays and prevent detection. However, this is a red flag for security personnel, who will likely conduct further inspections.
- Mimic common items: Place the prohibited item within an everyday object that is expected in the scanned area to reduce scrutiny. For example, hiding something in a laptop case or a toiletry bag. However, security personnel are trained to identify and investigate unusual shapes and contents, especially if something appears out of place.
- Advanced coatings: Apply advanced coatings that scatter or absorb X-rays differently, making objects less visible on scans. These coatings are typically used in specialized applications and may not be readily available.
Please note that attempting to hide items from airport security is illegal and can have serious consequences. The information provided here is for educational purposes only and should not be used for illegal activities.

Hack the X-ray software
X-ray machines, such as those used in airports, use a combination of hardware and software to function. Therefore, hacking the software could be a way to trick an X-ray machine. However, it is important to note that attempting to do so is illegal and unethical and can have serious consequences.
One way to potentially hack an X-ray machine is to gain access to the internal network of the organization operating the machines. For example, security researchers have demonstrated that it is possible to hack hospital X-ray machines by exploiting vulnerabilities in their network or WiFi hotspots. Once inside the network, an attacker can modify the images produced by the X-ray machines, potentially leading to misdiagnoses.
Another way to hack an X-ray machine is to directly target the software running on the machine itself. This may involve exploiting vulnerabilities in the software code or altering the calibration and error-correcting processes. By doing so, an attacker might be able to manipulate the images produced by the machine or even control its functionality.
To protect against such attacks, organizations should implement robust security measures. This includes using encryption to protect data transmitted between X-ray machines and workstations, as well as employing digital signatures and watermarking on X-rayed images to ensure their authenticity and detect any tampering. Additionally, regular software updates and patches can help address known vulnerabilities and reduce the risk of exploitation.

Exploit weaknesses in airport cybersecurity
Airport cybersecurity is a critical aspect of aviation security, but it often receives less attention than physical security measures. Here are some ways to exploit weaknesses in airport cybersecurity:
- Targeting Outdated Software and Hardware: Airports often use older software and hardware that may have known vulnerabilities. For example, researchers obtained a used X-ray introscope, which ran on Windows 98, an outdated operating system with many unpatched security flaws. Exploiting such outdated systems can provide unauthorized access to sensitive information or even allow for the manipulation of X-ray scan results.
- Bypassing Physical Security with Malware: Malware can be used to compromise the computers connected to X-ray machines. In one example, researchers developed malware that, when activated by a QR code on a piece of clothing, displayed an image of a different person on the X-ray scan, potentially allowing prohibited items to pass through undetected. This demonstrates how malware can be used to circumvent physical security measures.
- Exploiting Weak Password Practices: Airports may have weak password practices, such as storing operator passwords in plain text. This makes it easier for unauthorized individuals to gain access to secure systems, including those controlling X-ray machines and other critical infrastructure.
- Lack of Network Isolation: Airports often prioritize physical security over cybersecurity. This can result in a lack of network isolation, making it easier for an attacker to move laterally within an airport's network once they have gained initial access. This could potentially provide access to sensitive systems and data, including passenger information and flight details.
- Social Engineering and Insider Threats: Exploiting human weaknesses is another way to breach airport cybersecurity. Social engineering tactics can be used to manipulate airport staff, contractors, or even passengers into divulging sensitive information or providing unauthorized access. Additionally, insider threats, such as disgruntled employees, can exploit their privileged access to cause significant damage.
While some of these weaknesses may be challenging to address due to the complex nature of airport security, it is crucial to recognize these vulnerabilities and implement robust cybersecurity measures to protect critical infrastructure and ensure the safety of passengers and staff.

Frequently asked questions
You can politely inform the staff that your item cannot be X-rayed without being damaged and request a hand check. If they refuse, you can try showing them a printout of the relevant regulation, such as 49 CFR 1546.209, which applies to the TSA.
Researchers have found several methods to deceive former TSA X-ray scanners, such as concealing weapons by taping them to the side of the body or molding plastic explosives around a person's torso. Additionally, malware can be installed on the connected PC to manipulate the displayed images. However, these methods are illegal and highly dangerous.
Passing X-ray sensitive items through airport scanners may damage them, reduce their lifespan, or require time-consuming and expensive recalibration. For example, analog film is sensitive to X-rays and may be affected by the radiation.
