Airport X-Rays: Can They Alter Medication?

Airport security systems use metal detectors, backscatter x-ray machines, millimetre wave scanners, and cabinet x-ray machines to ensure the safety of passengers and staff. Some travellers may be concerned about the potential effects of baggage x-rays on their medications. However, according to Mohamed A. Jalloh, a spokesperson for the American Pharmacists Association, the x-ray machines emit a low level of radiation that has not been consistently shown to affect medications. If you are concerned, you can request a TSA agent to perform a manual security check.

X-ray machines emit low radiation

X-ray machines emit low levels of radiation. X-rays are a form of electromagnetic radiation, similar to visible light but with higher energy. They can pass through most objects, including the human body, and are used to generate images of tissues and structures inside the body. While X-rays have many beneficial medical applications, they also carry some risks associated with radiation exposure.

The radiation emitted by X-ray machines is known as ionizing radiation, which can interact with and damage living cells. This radiation has sufficient energy to break up molecules and damage DNA, potentially leading to cancer years later. However, the extent of radiation exposure from airport X-ray scanners is relatively low.

A standard carry-on baggage X-ray scanner exposes items to approximately 15% of the daily exposure to background radiation. This background radiation is naturally occurring and comes mainly from the radioactive decay of isotopes. Studies have shown that even 10 consecutive passes through an X-ray scanner did not noticeably affect the viability and proliferative capacity of hematopoietic stem cells.

While the impact of X-rays on medications is not extensively studied, the low radiation levels emitted by airport X-ray machines are unlikely to affect most medications. If there were a potential issue, medications would likely carry a relevant warning label. Additionally, the Transportation Security Administration (TSA) allows travellers to request a manual security check instead of passing medications through an X-ray scanner.

X-rays are unlikely to affect medications

The FDA requires that all machines are correctly calibrated and maintained, and their rules apply to all X-ray equipment at airports, as well as medical equipment and other uses of radiation-emitting equipment. Furthermore, safety measures are in place to ensure that airport security systems do not expose workers and travellers to high levels of ionizing radiation.

In the case of cabinet X-ray systems, which are used to screen luggage and carry-on items, the thick walls of the enclosed cabinet and lead curtains at the entry and exit points of the cabinets keep radiation from escaping. These machines must meet strict standards regarding radiation escape and must also have locks, warning lights, and labels to ensure safety.

A study by Nagoya City University in Japan found that exposure to X-rays did not affect the pharmaceutical quality of the drug content. The samples exposed to X-rays exhibited almost the same profile in formulation tests (dissolution test, disintegrating test, and hardness test) as control samples (0 Gy). The combination of X-ray exposure with accelerated temperature and humidity tests (six months) also did not affect the pharmaceutical quality.

If you are concerned about the potential effects of X-ray screening on your medications, you can request a TSA agent to perform a manual security check instead.

CT scanners can result in greater exposure than carry-on baggage scanners

X-ray scanners are commonly used in airport security to inspect baggage and ensure the safety of passengers and staff. While concerns have been raised about the potential impact of these scanners on medications, the effects are generally considered to be minimal.

Computer Tomography (CT) scanners, in particular, have been the subject of scrutiny due to their use of X-ray technology to create detailed 3D images of baggage contents. These scanners are used for both checked and carry-on baggage and have been hailed as the most advanced technology available for threat detection in airports.

While CT scanners are highly effective in ensuring security, they have been found to result in greater radiation exposure compared to conventional carry-on baggage scanners. The higher radiation exposure is due to the nature of CT technology, which involves capturing multiple 2D X-ray images from different angles and then assembling them into a 3D representation. This process allows for a more comprehensive analysis of the bag's contents but also leads to increased radiation exposure.

The impact of CT scanners on medications has been a specific area of concern. According to Michael M. White, a Professor and Chair at Drexel University College of Medicine, the radiation exposure from a single pass through a CT scanner is less than a year's worth of background radiation. Therefore, it is unlikely to cause any significant damage to medications. However, White recommends avoiding CT scanners if possible and keeping all medications in carry-on luggage to minimize potential risks.

In summary, while CT scanners can result in greater radiation exposure than conventional carry-on baggage scanners, the level of exposure is still considered safe for medications. Nonetheless, passengers with concerns can opt for a manual inspection of their carry-on items instead of passing them through a scanner, as per Federal Aviation Administration regulations.

Regulations allow for manual searches instead of X-ray scanning

Airport security systems use metal detectors, backscatter X-ray machines, millimeter wave scanners, and cabinet X-ray machines to ensure the safety of passengers and staff. Some of these devices use ionizing radiation to scan luggage, while others use non-ionizing radiation. Safety measures are in place to ensure that staff and passengers are not exposed to high levels of ionizing radiation.

Non-ionizing radiation has enough energy to move atoms in a molecule or cause them to vibrate, but not enough to remove electrons from atoms. Metal detectors and millimeter wave machines use low-energy, non-ionizing radiation to scan surfaces. Millimeter wave machines are particularly useful for security as they can show hidden threats such as guns and knives.

Ionizing radiation, on the other hand, has enough energy to knock electrons out of atoms. Backscatter X-ray machines use very low-energy X-rays to detect threats such as weapons or explosives that a person might be carrying under their clothing. Cabinet X-ray machines are used to screen luggage and carry-on items, and the machines are designed to meet strict standards to limit radiation escape.

While the risk of health effects from X-ray and millimeter wave screening is very low, passengers who are concerned about this process can opt for a manual search instead. Regulations allow for carry-on items to be searched by hand, and passengers can request this alternative method if they are worried about potential damage to their medications.

The Transportation Security Administration (TSA) is responsible for ensuring the safety of passengers and staff at airports. Their screening equipment must meet the requirements set by the Food and Drug Administration (FDA) to limit radiation exposure. The TSA conducts regular testing and maintenance of their equipment to adhere to federal, state, and local safety standards.

Safety measures are in place to protect workers and travellers from high-level radiation exposure

Airport security systems use metal detectors, backscatter X-ray machines, millimetre wave scanners, and cabinet X-ray machines to ensure the safety of travellers and workers. Some of these devices, such as metal detectors, use non-ionizing radiation to scan for items that may pose a security threat. Non-ionizing radiation does not have enough energy to remove electrons from atoms. In contrast, ionizing radiation, which is used by some other devices, has enough energy to knock electrons out of atoms.

Additionally, the US Environmental Protection Agency (EPA) provides general radiation guidance to Federal Agencies, and the US Occupational Health and Safety Administration (OSHA) has regulations on worker safety from radiation in the workplace. Transportation Security Administration (TSA) agents are also present at security checkpoints to ensure the safety of travellers.

Regarding the impact of X-rays on medications, there is limited data on the sensitivity of specific therapeutic agents to radiation damage. However, X-ray machines used in airport security emit low levels of radiation that have not been consistently shown to affect medications. A study found that 10 consecutive passes through an X-ray scanner had no noticeable effect on the viability and proliferative capacity of haematopoietic stem cells. Similarly, another study found that X-ray exposure did not affect the pharmaceutical quality of drug tablets. Nevertheless, if travellers are concerned about potential damage to their medications, they can request a TSA agent to perform a manual security check.
