Dangers of EM waves & protective measures
Over-exposure harms by band: microwaves heat tissue inside the body, infrared burns the skin, ultraviolet damages surface cells and can blind, and gamma with x-rays can trigger cancer and mutation. Against these, engineers and clinicians build simple barriers: metal oven walls, gloves, sunglasses and sunscreen, minimal doses and badge-monitored exposure.
What you know already
The same spectrum that carries phone calls and photographs can damage the body that receives them. Frequency is the lever: beyond the visible band the energy of each wave grows large enough to ionise atoms, and the hazards climb with it. This lesson matches each band to its danger and to the simple measures that cut the risk.
Key points of understanding
- Microwaves can cause internal heating of body tissue.
- Infrared can burn the skin.
- Ultraviolet can damage surface cells and cause blindness.
- Gamma rays and x-rays can kill cells, causing cancer and mutation.
- Protective measures include metal oven walls, protective gloves, sunglasses, sunscreen, minimal doses and radiation badges.

Radiation badges are used by people working closely with radiation to monitor exposure
