I've always wondered if substances going through airport xrays would have some effect on their structure, what do you think?
It is entirely a matter of intensity, duration, and repetition
Summary:
1. The Sun (The Borderline Case)
Time exposure makes the difference
While visible light is completely safe, the Sun emits Ultraviolet (UV) rays. UV light sits exactly on the border of the ionizing spectrum. It has short enough wavelengths to pack a punch. It physically damages skin cells and causes sunburns, which is why it can lead to structural DNA changes (skin cancer) over time.
However Infra-Red light is fine when you adapt the wavelength and the duration.

2. Cell Phone in a Pocket (Trouser or Breast Pocket)
Ionization Capability: Absolutely zero.
Warmth has a incidence (thermal effect).
NB: Everybody won’t agree here. I don’t put mine in a trouser pocket since it has an influence on my hand when I use it for a long time on internet.
3. Public Electric Streetlight
Zero impact if you’re not electrical sensitive (50Hz to 60Hz).
NB: It's different if it's a high-voltage pylon. Cows whose water trough is under this type of pylon produce significantly less milk.
4. Airport Scanners
Too short to have an impact. + low level on the scale.
5. Dental xRays:
Yes.
I’ve asked Google to develop some points. Has to be confirmed by another source since we can’t trust AI, as you already know. AI flatters you and sometimes invents / often extrapolates to avoid contradicting itself.
The Physics of Exposure
• Intensity: Both airport scanners and dental X-rays use extremely low-intensity beams. They are engineered to look only at surface levels or thin jaw bones, requiring a fraction of the power used for deep-tissue medical scans like CT scans. [1, 2]
• Duration: The exposure time is measured in milliseconds. The beam clicks on and off almost instantly, minimizing the window of interaction with your cells.
• Repetition: For the average person, these events happen once or twice a year. The human body has highly efficient, constant cellular repair mechanisms that easily fix the minor, isolated cellular stress caused by such infrequent, low-dose exposures. [1]
The Exception: Developing Life
Your concern about pregnant women is scientifically spot-on.
• Rapid Cell Division: A fetus is in a state of rapid development. Cells are dividing constantly to form organs and body structures.
• Higher Sensitivity: Cells undergoing mitosis (division) are significantly more vulnerable to DNA alterations from ionizing radiation.
• Precautions: This is why dental offices use extra precautions, like lead aprons that cover the abdomen, or delay non-urgent routine X-rays until after delivery, purely as a protective measure for that sensitive stage of life. [1, 2]
For an adult, a few routine exposures do not accumulate enough energy to alter your body's structure.
