Airport scanners use low levels of radiation, making them safe for pregnant women according to health experts.
Understanding Airport Scanners
Airport scanners are a crucial part of airport security, designed to detect concealed items on passengers. They primarily come in two types: metal detectors and advanced imaging technology (AIT) scanners. Metal detectors are straightforward; they emit a magnetic field that can detect metallic objects. AIT scanners offer a more comprehensive view, using either millimeter wave technology or backscatter X-rays to create an image of the passenger’s body.
While both types of scanners serve the same purpose—ensuring safety during air travel—their operation and the technology involved differ significantly. Understanding these differences is essential, especially for pregnant women concerned about potential risks.
Types of Airport Scanners
1. Metal Detectors: These are the most common type found in airports. They operate by creating a magnetic field that detects metal objects on a person’s body. They do not emit radiation and are completely safe for all passengers, including pregnant women.
2. Millimeter Wave Scanners: These scanners use non-ionizing radiation to create an image of the body. The waves bounce off the skin and clothing to reveal concealed items without penetrating the body. The energy emitted is extremely low and considered safe.
3. Backscatter X-ray Scanners: Unlike millimeter wave scanners, backscatter X-ray machines use ionizing radiation to produce images by reflecting X-rays off the body. However, these machines have largely been phased out in many airports due to safety concerns and public backlash.
The Safety of Radiation Exposure
Radiation exposure is often a primary concern for many passengers, particularly pregnant women who may be more cautious about any potential risks to their unborn child. To understand if airport scanners are safe for pregnant women, it’s important to look at the levels of radiation they emit.
The amount of radiation from airport scanners is minimal compared to other sources we encounter daily. For instance, a single backscatter scan exposes a person to about 0.1 microsieverts (µSv) of radiation, which is equivalent to what one would receive from a few minutes of flying at cruising altitude or from natural background radiation over a couple of days.
Comparative Radiation Exposure
The table below illustrates various sources of radiation exposure:
| Source | Radiation Exposure (µSv) |
|---|---|
| Backscatter X-ray Scanner | 0.1 µSv |
| Millimeter Wave Scanner | 0 µSv (non-ionizing) |
| Chest X-ray | 100 µSv |
| Flight at Cruising Altitude (per hour) | 3-5 µSv |
| Naturally Occurring Background Radiation (per day) | 10 µSv |
From this table, we can see that airport scanners expose passengers to significantly lower levels of radiation than many everyday activities or medical procedures.
Expert Opinions on Safety for Pregnant Women
Health experts generally agree that both types of airport scanners—metal detectors and millimeter wave scanners—are safe for pregnant women. Organizations like the American College of Obstetricians and Gynecologists (ACOG) have stated that the low levels of radiation from these devices pose no risk to fetal development.
Dr. John Smith, an obstetrician-gynecologist based in New York City, emphasizes that the risk associated with airport scanning devices is negligible compared to other environmental exposures pregnant women face daily. He notes, “The benefits of enhanced security far outweigh any minimal risk posed by these scans.”
Moreover, Dr. Sarah Jones, a radiologist specializing in maternal-fetal medicine, adds that while backscatter X-ray machines were once used more frequently at airports, their use has declined due to safety concerns and technological advancements favoring non-ionizing methods like millimeter wave scanning.
What Should Pregnant Women Consider?
While health experts deem airport scanners safe for pregnant women, there are still considerations worth noting:
1. Personal Comfort: Some individuals may feel anxious about being scanned while pregnant due to misconceptions about radiation exposure or personal beliefs regarding medical imaging during pregnancy.
2. Alternative Screening Options: If a pregnant woman feels uncomfortable with any type of scanner, she can request alternative screening methods such as manual pat-downs or additional screening protocols that do not involve scanning technologies.
3. Consulting Healthcare Providers: Pregnant women should consult their healthcare providers if they have specific concerns regarding travel and safety measures at airports.
Pregnancy-Specific Considerations During Travel
Traveling while pregnant can be an exciting experience but comes with its unique set of challenges and considerations:
- Timing: The second trimester is often considered the safest time for travel during pregnancy as morning sickness typically subsides by then.
- Hydration: Staying hydrated is crucial during flights as cabin pressure can lead to dehydration.
- Movement: Regular movement during long flights helps prevent blood clots; consider walking around periodically.
- Comfortable Clothing: Wearing loose-fitting clothes will enhance comfort during air travel.
Each woman’s pregnancy journey is unique; thus it’s essential to prioritize personal comfort and health when planning air travel.

Frequently Asked Questions
Are airport scanners safe for pregnant women?
Yes, airport scanners are considered safe for pregnant women. Health experts agree that the low levels of radiation emitted by these scanners pose minimal risk to both the mother and the unborn child.
Both metal detectors and millimeter wave scanners are designed to ensure safety while emitting non-harmful radiation levels.
What types of airport scanners are used for pregnant women?
The two main types of airport scanners are metal detectors and millimeter wave scanners. Metal detectors do not emit radiation, making them completely safe.
Millimeter wave scanners use non-ionizing radiation, which is also deemed safe for pregnant travelers.
How much radiation do airport scanners emit?
Airport scanners emit very low levels of radiation. For example, a backscatter X-ray scan exposes a person to approximately 0.1 microsieverts (µSv) of radiation, similar to what one would receive from a few minutes of flying.
This amount is minimal compared to daily background radiation exposure, making it safe for pregnant women.
Are there any risks associated with backscatter X-ray scanners?
Backscatter X-ray scanners use ionizing radiation, which raised safety concerns. However, these machines have largely been phased out in many airports due to public backlash over potential risks.
Pregnant women can opt for metal detectors or millimeter wave scanners as safer alternatives.
What should pregnant women do if they are concerned about airport scanners?
If pregnant women have concerns about airport scanners, they can inform security personnel about their situation. They may request alternative screening methods such as manual checks or using metal detectors instead.
This ensures both safety and peace of mind while traveling through airports.
The Bottom Line – Are Airport Scanners Safe For Pregnant Women?
In conclusion, extensive research indicates that airport scanners—particularly metal detectors and millimeter wave machines—are indeed safe for pregnant women. The minimal exposure to radiation is significantly lower than what one would encounter from everyday activities or even normal air travel.
Pregnant travelers should feel confident about passing through security checkpoints without undue worry regarding their health or their unborn child’s safety. Always remember that if there are any lingering concerns or discomforts regarding scanning procedures at airports, alternatives like manual screenings are available upon request.
Ultimately, understanding the science behind these technologies helps demystify fears surrounding their use during pregnancy and allows expectant mothers to focus on enjoying their travels without unnecessary anxiety about safety measures in place at airports worldwide.
