For photons of 50 kev, 500 kev, and 5 mev, what will be the most likely init interaction with tissue?

50 KeV

Explanation:

50 KeV will be the most likely initial interaction with tissue.

Because Higher the energy lesser will the interaction with tissues, Because it will penetrate through tissue more easily in a very lesser time Whereas the photon with least energy will take more time to penetrate through the tissue, hence, higher interaction with tissue.

powerful computers now, not then

here are some information of the future of geothermal energy:

-the future of geothermal energy can pretty much be summed up with a single word: more

-scientists plan in going deeper than 120 meters

-we are hoping that one day, we will get all of our energy from renewable energy sources such as geothermal energy

hope this !
