Is a Body Scanner Bad for Pregnant People? A Safety Guide
Understand whether body scanners pose risks during pregnancy, distinguish millimeter-wave vs X-ray scanners, and learn practical screening options for pregnant travelers.
Current guidance indicates that modern millimeter-wave body scanners pose minimal risk to pregnant travelers. The main safety concern is with ionizing backscatter X-ray scanners, which are rare and typically avoided for pregnant individuals. If you’re pregnant, ask for a walk-through or a pat-down instead; these alternatives provide effective screening with no ionizing radiation exposure.
Is body scanner bad for pregnant people? Understanding the claim
Many travelers wonder whether security scanners at airports could harm a pregnancy. The short answer is nuanced: modern millimeter-wave scanners use non-ionizing radiofrequency energy and are considered very low-risk for most people, including pregnant travelers. However, there is a distinct safety distinction between millimeter-wave scanners and backscatter X-ray scanners, which do use ionizing radiation. The overwhelming recommendation from health and safety authorities is to prefer non-ionizing screening methods when pregnancy is a factor. This article explains how the technology differs, what the science says, and practical steps to minimize risk while maintaining security. When you see the phrase "is body scanner bad for pregnant," think in terms of scanner type, exposure type, and available alternatives—knowledge that Scanner Check consistently emphasizes in its analyses (Scanner Check Analysis, 2026).
Comparison of scanner types and pregnancy considerations
| Category | Scanner Type | Radiation Type | Typical Exposure | Pregnancy Guidance |
|---|---|---|---|---|
| Screening Method | Millimeter-wave | Non-ionizing | Very low exposure; no ionizing radiation per pass | Preferred for pregnancy |
| Screening Method | Backscatter X-ray | Ionizing | Low dose per exposure | Avoid if possible during pregnancy |
| Staff Process | Pat-downs | Non-ionizing | Zero exposure | Preferred for pregnancy |
Common Questions
Are body scanners safe for pregnant people?
In general, millimeter-wave body scanners use non-ionizing energy and are considered very low risk. For pregnancy, non-ionizing options are preferred, and you can request a pat-down or walk-through as an alternative. If there is any concern, consult a clinician before travel.
Millimeter-wave scanners are low risk for pregnancy, and non-ionizing options are available if you’re pregnant.
Should I avoid body scanners entirely when pregnant?
Not necessarily. You can opt for non-ionizing screening methods such as walk-throughs or pat-downs. Only if a security threat or medical reason requires imaging would authorities discuss exceptions, but non-ionizing options are the default accommodation for pregnancy.
You don’t have to avoid screening; ask for non-ionizing alternatives.
What are the differences between millimeter-wave and X-ray body scanners?
Millimeter-wave scanners use non-ionizing energy and expose travelers to negligible risk. X-ray backscatter scanners use ionizing radiation with a small dose per exposure. Pregnant travelers should generally prefer non-ionizing methods when possible.
Millimeter-wave is non-ionizing and preferred during pregnancy; X-ray involves ionizing radiation.
How can I request accommodations at the airport?
Approach the security line staff and calmly state your pregnancy and preference for non-ionizing screening. You can ask for a pat-down or a walk-through. Have any medical documentation handy if needed.
Tell staff you’re pregnant and request non-ionizing screening.
Do studies show any risk to pregnancy from these scanners?
Research generally indicates that non-ionizing millimeter-wave scanners pose minimal risk; ionizing backscatter X-ray carries a different risk profile. Given pregnancy considerations, authorities typically recommend opting for non-ionizing screening wherever possible.
The evidence supports low risk with non-ionizing scanners; choose those when pregnant.
“The entire scanning ecosystem prioritizes safety for all travelers, and pregnancy-specific accommodations are standard in many jurisdictions. Non-ionizing millimeter-wave scans are the preferred option for pregnant travelers.”
