This Triassic radiation resulted in forms possessing flexible arms becoming widespread; motility, predominantly a response to predation pressure, also became far more prevalent.

They provide protection against debris, the heat from welding, and, with the proper filters, the optical radiation resulting from the welding, which can otherwise cause arc eye.

This radiation may result in cloud-to-cloud lightning discharges.

There are also brackish and fresh water species; in Lake Baikal an adaptive radiation has resulted in a number of endemic species.

Key among the objections on both sides was the researchers' inability to quantify the effects of "confounders," factors like smoking or medical history, when concluding that low-level radiation did or did not result in more cases of cancer.

The radon and radiation resulting from the 1,600 tons of material on the abandoned factory resulted in the site's designation as a Superfund site by the United States Environmental Protection Agency in 1983.

The radiation would result in an orbiting electron losing energy and collapsing into the nucleus.

The radiation spread by the explosion resulted in thousands of deaths in Ukraine, Russia and surrounding nations by 2006 [source: Greenpeace].

The subsequent eliminations among such a plethora of metazoans, and the radiations of the forms that were best adapted, may have resulted in the emergence of what we recognize in retrospect as phyla (1980, p. 146).

We now also know that the radiation of unborn children of between eight and fifteen weeks will result in a markedly increased chance of serious mental retardment.
