Radiation-emitting particles can then travel afar, depending on the speed and direction of the prevailing wind.

放射性微粒形成之后，可以飘到很远的地方，具体多远就看主风的速度和方向。

From the electromagnetic radiation, you can clearly determine direction.

从电磁辐射中，你可以清楚地决定研究方向。

If the cosmic radiation has a preferred direction, that assumption may have to go - along with our best theories about cosmic history.

如果宇宙的辐射有一个它们所认可的方向，上面的假设就可能必须放弃——随之而放弃的是我们对宇宙历史的最佳理论。

The distribution of the detectors triggered allows the direction of the Cherenkov radiation, and therefore the flight direction of the muon, to be worked out.

ECONOMIST: Neutrino astronomy

According to the physicists, when a large black hole captures a smaller object like a medium-sized star the process causes gravitational radiation to be emitted in a preferential direction.

Even if the winds change direction, which is unlikely, fears of massive radiation poisoning throughout the region are vastly overblown.
