Full-body scanners: an invasion of privacy?
Full-body scanners have been the subject of much debate since their introduction in airports. While some argue that they are necessary for security purposes, others view them as an invasion of privacy. So, can you refuse a full-body scan at the airport, and what are the alternative options?
Firstly, it is important to know your rights. Passengers passing through a Transportation Security Administration (TSA) checkpoint in the United States are legally allowed to opt out of the body scanner for any reason. However, alternative screening methods must be employed to ensure the safety of commercial flights. In the UK, passengers selected at random for a full-body scan can also opt out and request an alternative screening method.
If you choose to opt out of the full-body scanner, you will be subjected to a full-body pat-down. This involves a manual screening by a TSA agent of the same gender as the passenger. Some travellers may prefer this option, especially if they have concerns about medical conditions or the radiation emitted by the scanners. However, others may find this method even more invasive than the scanner. It is worth noting that while most TSA agents are professional, some travellers have reported feeling uncomfortable during the pat-down process due to the attitude of the agent. Additionally, the pat-down may take place in a public area, although travellers can request for it to be done in a private room.
Another option for travellers who wish to avoid the full-body scanner is to sign up for TSA Precheck (in the US) or apply for a Registered Traveller Service (in the UK). These programmes allow travellers to undergo expedited screening, where they can keep their personal items packed and their shoes on, and often avoid body scanners altogether.
Ultimately, the decision to undergo a full-body scan or opt for an alternative screening method is a personal one. While some may feel that the scanners are an invasion of privacy, others may prefer the convenience and speed of this screening method. By raising awareness and encouraging dialogue, it is possible to find a balance between respecting personal choice and maintaining security standards in airports.

Opting out: what are my rights?
Passengers at airports are selected at random to undergo a full-body scan. However, you can refuse to go through a full-body scanner and opt for a full-body pat-down instead. This is a manual screening by a TSA agent of the flyer's gender, intended to ensure that a traveler is not carrying contraband aboard an aircraft. While some pat-downs take place in public areas, you can request to be screened in a private room.
If you have concerns about your physical or mental health, you may want to consider opting out of the full-body scan. While there is no evidence that body scanners affect pacemakers or implanted ICD devices, those who are concerned about their condition may want to choose an alternative option. If you have concerns prior to travel, you can contact the Federal Security Officer at the airport to discuss arrangements ahead of your travels.
If you are concerned about the safety of your belongings, you can request to keep them with you during the screening. However, it is recommended that you keep important items such as credit cards, passports, and driver's licenses on your person at all times.
It is important to note that the TSA is still responsible for ensuring the safety of commercial flights, which requires screening for all commercial passengers. Knowing all the options available can help travelers make the best decisions for their personal well-being.

Are body scanners safe for everyone?
The safety of body scanners has been a topic of debate, with concerns about the potential health risks associated with the radiation emitted by these devices. There are two main types of body scanners used in airports: millimeter-wave scanners and backscatter X-ray scanners.
Millimeter-wave scanners use non-ionizing electromagnetic radiation in the extremely high-frequency radio band, which is similar to the radiation used by wireless data transmitters. These scanners do not generate ionizing radiation, and the current evidence suggests that they do not have any adverse health effects. However, it is important to note that long-term studies on the safety of millimeter-wave scanners have not yet been conducted.
Backscatter X-ray scanners, on the other hand, use low-dose ionizing radiation to detect metallic and non-metallic objects hidden under clothing or in body cavities. The radiation dosage received from these scanners is typically between 0.05 and 0.1 μSv, which is significantly lower than the dosage from a standard X-ray. However, due to concerns about the potential health risks, multiple countries, including European nations, have banned the use of backscatter X-ray machines in airports.
While some radiation safety authorities have stated that they are not aware of any evidence that full-body scans are unsafe, other organizations, such as the International Atomic Energy Agency and Nuclear Energy Agency, recommend against using ionizing radiation on certain populations like pregnant women and children. Additionally, opponents of body scanners argue that there is a lack of long-term data on the health effects of both backscatter X-ray and millimeter-wave scanners.
In certain countries like Australia, there is a no-opt-out policy for airport screening, including body scans. However, individuals with medical or physical conditions that prevent them from undergoing a body scan will be offered alternative screening methods. Similarly, infants and young children below a certain height threshold are exempt from body scans.
Overall, while there is ongoing debate and conflicting opinions regarding the safety of body scanners, the current consensus among experts is that the radiation exposure from millimeter-wave scanners is minimal and unlikely to cause harm, especially considering the infrequent nature of passing through airport security. However, individuals with specific medical conditions or concerns should consult with their healthcare providers for personalized advice regarding airport body scanners.

What are the alternatives to a body scan?
If you refuse a body scan at the airport, alternative security screening protocols are in place to ensure your safety and that of other passengers. The primary alternative to a full-body scan is a full-body pat-down. This is a thorough procedure, and you should always be polite and respectful during the process.
The full-body pat-down is a comprehensive search conducted by a TSA agent. They will use the back of their hands to feel for any suspicious items or objects that could pose a security risk. This method is effective in detecting both metallic and non-metallic threats and is often employed when individuals opt out of body scans or in cases where the body scanner malfunctions or raises false alarms.
It is important to note that the full-body pat-down is not just a simple pat-down of the outer clothing. TSA agents are trained to perform a thorough search, which may include touching sensitive areas of the body. This is done professionally and respectfully, with the agent and the passenger of the same gender.
Additionally, passengers who refuse body scans may be subjected to further screening procedures, such as additional questioning, baggage checks, or other security measures deemed necessary by the TSA. These measures are in place to ensure the safety and security of all passengers and staff.
While the body scan technology has evolved to address privacy concerns, some passengers may still prefer the alternative of a full-body pat-down. It is important to remain cooperative and respectful throughout the security screening process, regardless of the method employed.

How does a body scanner work?
A full-body scanner is a device that detects objects on or inside a person's body for security screening purposes, without physically removing clothes or making physical contact. Full-body scanners can detect both metallic and non-metallic objects, which makes them more effective than metal detectors. They can also detect swallowed items or items hidden in body cavities.
There are three distinct technologies used in full-body scanners: millimeter-wave scanners, backscatter X-ray scanners, and through-body X-ray machines. Millimeter-wave scanners use non-ionizing electromagnetic radiation in the extremely high-frequency radio band, which is a lower frequency than visible light. This type of scanner produces a 3D image of the subject and does not emit any radiation dose, making it safe for use.
Backscatter X-ray machines, on the other hand, use X-rays to create a 2D image of the exterior of a person's body. While these machines emit a low dose of radiation, it is still significantly lower than the dose received from a medical X-ray. The radiation dose from a backscatter X-ray scan is less than 0.1 micro sievert (µSv) per scan, which is much lower than the dose from a typical dental X-ray, which is 10 µSv.
Through-body X-ray machines are capable of seeing through flesh and deliver real doses of radiation. These scanners have been supplied by the U.S. government to airports in Ghana and Nigeria, raising concerns about the potential health risks and ethical implications of this technology.
SafeView, a Silicon Valley startup, was the first company to commercialize millimeter-wave body scanner technology. Their scanners were first implemented on a large scale at Schiphol Airport in the Netherlands in 2007. Since then, full-body scanners have been adopted by airports, border crossings, ferry landings, railway stations, government buildings, and commercial buildings worldwide.
