Sentences with phrase «delivering high energy radiation»

Radiation therapy machines treat cancer by delivering high energy radiation to a tumor, killing the tumor cells.

Not exact matches

Among the advances that have already been made are linear accelerators that generate higher - energy radiation beams, and more versatile patient tables that enable radiation doses to be delivered to the tumor from a variety of angles and directions.

A huge laser delivers a large amount of energy in a short time to heat the walls of the larger chamber, and the radiation emitted from those walls in turn drives the small capsule to a very small size, increasing the density of the gases inside to much higher density than lead and heating it at the same time to very high temperatures required for fusion to occur.

In other words, * we can observe the increase of CO2 in atmosphere above the ocean, * CO2 absorbs some part of the outgoing radiation from the surface of the ocean which increases somewhat the temperature of the air * The increasing of temperature causes the (slight) increase of the (already existing) back radiation * This (now increased) back radiation is absorbed by the surface skin layer of the ocean which means that the energy delivered by the back radiation to the surface skin layer is now slightly higher * This additional energy will now be distributed over the channels that are participating in the heat transfer from the absorbing surface skin layer to both the air above the skin layer and the bulk of the ocean.
