Explaining Temperature Increase with Antenna and Tissue

Click For Summary
SUMMARY

The discussion centers on the relationship between radio frequency emissions from an antenna and temperature increases in biological tissue. The antenna emits frequencies of 1e7 Hz, 3e7 Hz, and 6e7 Hz, resulting in the same temperature increase, which raises questions about the underlying causes. Key explanations include consistent power output, varying absorption rates of the tissue, and the influence of an electric space heater beneath the tissue. Additionally, the biological tissue's potential to generate thermal energy due to its living or decomposing state is highlighted as a factor.

PREREQUISITES
  • Understanding of Specific Absorption Rate (SAR)
  • Knowledge of radio frequency emissions and their effects
  • Familiarity with biological tissue properties
  • Basic principles of thermal energy generation
NEXT STEPS
  • Research the effects of radio frequency on biological tissues
  • Study Specific Absorption Rate (SAR) calculations and implications
  • Explore thermal energy generation in living tissues
  • Investigate experimental design for control samples in radiation studies
USEFUL FOR

Researchers in bioelectromagnetics, biomedical engineers, and anyone studying the effects of radio frequencies on living tissues will benefit from this discussion.

Hi;

Let's imagine that I have an antenna and a biological tissue.
The antenna emits the frequency of 1e7 Hz and I have a temperature increase x.
When the antenna emits the frequency of 3e7 and 6e7 Hz the temperature increase is the same.
How can I explain?
 
Science news on Phys.org
Several possible explanations:
1. Same power output.
2. Same sbsorption.
3. The temperature increase was due to the electric space heater placed under the biological tissue and had nothing to do with the radio waves.

The power output of the antenna is the same, but the absortion of the tissue is different, and there is no way that the temperature increase can only be related to tissue.
Anyway, thaanks!

How can you be sure of this?

4. The biological tissue is living (or decomposing) and self-generating thermal energy.

Is there a control sample that is not irradiated?

This is silly. You’re asking us to explain something you imagined! Imagine that!

I imagine no temperature change. My imagination is as valid as yours.

My imaginary space heater disagrees. ?:)

Because the SAR (Specific Absorption Rate) is differente

This makes a lot of sense
Thank you
