Less harmful electromagnetic waves

Click For Summary
SUMMARY

The discussion centers on the search for electromagnetic waves that can penetrate human tissues while being blocked by specific materials, with a focus on less harmful alternatives to X-rays. Participants confirm that radio waves can pass through the human body but can be obstructed by sufficient thickness of metal or conductive materials. The conversation also touches on the diffraction properties of radio waves, suggesting that while they can be blocked, they may also bend around obstacles. Overall, the need for safer electromagnetic wave options is emphasized.

PREREQUISITES
  • Understanding of electromagnetic wave properties
  • Knowledge of material science, specifically regarding conductivity
  • Familiarity with X-ray and gamma radiation characteristics
  • Basic principles of wave diffraction
NEXT STEPS
  • Research the properties of radio waves and their interaction with various materials
  • Explore alternatives to X-rays, such as terahertz radiation
  • Investigate the effects of electromagnetic waves on human tissues
  • Learn about advancements in shielding materials for electromagnetic radiation
USEFUL FOR

This discussion is beneficial for physicists, material scientists, medical professionals, and anyone involved in the study or application of electromagnetic radiation and its effects on human health.

Hi guys,
I am too old to remember basic knowledge about electromagnetic waves :D
I am looking for a combination of an electromagnetic wave and a material such that the wave can pass through human tissues, but it is blocked by the material. All I know is that X-ray/gamma can penetrate human body but is absorbed by metals/lead. Are there any such other combination which are less harmful than X-ray. I have gone through Wikipedia for few hours but still have not found the answer yet.
Could you please help me.
Thank a lots.

Radio waves pass easily through the human body, but are blocked by an appropriate thickness of metal (or any conductor).
 
Thank you for the answer!
But I think radio waves are able to diffract around the object, is that right?
