| Molecules may change their rotational energy levels by absorbing energy from electromagnetic radiation in the microwave region of the spectrum. |
| The gases, especially carbon dioxide and methane, absorb the Earth's heat radiation and thus warm the surface, just as a blanket traps body heat. |
| Three nerves seem to be particularly prone to radiation injury that results in radiation neuritis. |
| This foil doesn't do very well in the air, but it protected it from meteorites and from the ultraviolet radiations from the sun. |
| A radioactive source will emit these radiations at various frequencies, depending on its activity and its decay mode. |
| Rate variation among lineages is the footprint of selection and can be indicative of species radiations or differential structural constraints. |
