These effects decrease in power far more quickly with distance than do the far-field radiation effects.

While deterministic radiation effects are a possibility, radiation burns are not typical of standard fluoroscopic procedures.

Vacuum tubes are much less sensitive to radiation effects.

As a result, he was in charge of space radiation effects on space craft and their components.

The field includes the study of photosynthesis, photomorphogenesis, visual processing, circadian rhythms, bioluminescence, and ultraviolet radiation effects.
