This causes energetic and short range alpha radiation from the boron to bombard the tumor.

Certain substances produce light when they are illuminated by more energetic radiation, a process known as fluorescence.

Some substances emit light slowly after excitation by more energetic radiation.

The vast and growing cloud of energetic ionizing radiation that had been spewed out by the solar flare soon engulfed them both.

There was never any worry in those days about possible dangerous physiological effects of energetic radiation.

They stop some of the lighter particles, he said, letting detectors pick up more energetic radiations.

In addition to light, mentioned above, semiconductor diodes are sensitive to more energetic radiation.

Less energetic radiation, such as visible light, only causes excitation, not ionization, which is usually dissipated as heat with relatively little chemical damage.

Thermospheric temperatures increase with altitude due to absorption of highly energetic solar radiation.

The physicists wanted to study how energetic radiation and subatomic particles streaming in from the sun and stars interacted with the thin Martian atmosphere.
