Explaining Temperature Increase with Antenna and Tissue

AI Thread Summary
The discussion revolves around the effects of radio frequency emissions on biological tissue, specifically examining temperature increases at different frequencies. Participants propose several explanations for the observed temperature changes, including consistent power output, varying absorption rates of the tissue, and the influence of an electric space heater. There is skepticism about the validity of the scenario, with some arguing that the imagined conditions lack scientific grounding. The concept of Specific Absorption Rate (SAR) is mentioned as a factor in understanding tissue response to different frequencies. Overall, the conversation highlights the complexities of measuring thermal effects in biological tissues under varying conditions.

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.

Zz.

My imaginary space heater disagrees. ?:)

Because the SAR (Specific Absorption Rate) is differente

This makes a lot of sense
Thank you
