I understand femtotechnology steel is supposed to have an infinite lifespan. Titanium was used to manufacture the space shuttle. I know based on similar eye nerves were repaired via high specification radiation. I also read a femtotechnology barrier can prevent radiation passing through. I wanted to use as a treatment barrier to help destroy cancer via the femtotechnology barrier. I questioned if high heat radiation could cause cells to regenerate, I wondered if the radiation could cause cancerous cells to spread as well. I read cells can become radiation resistant.
