The pronunciation guide uses the ARPABET phonetic system—the same system used in speech recognition and text-to-speech applications.

Vowel Examples:
AE1 = cat, bat
EH1 = bed, head
IY1 = see, me
OW1 = go, boat
UW1 = boot, do
Stress Numbers:
0 = no stress (unstressed)
1 = primary stress (loud)
2 = secondary stress (medium)
Example:
AH0 TH IY1 N AH0
= a-THEE-na (Athena)

The stressed syllable (marked with 1) is pronounced louder and clearer than others.

Quick Definition

Energy transmitted as waves or particles. It includes forms such as light, heat, radio waves, and ionizing emissions.

Detailed Definition
Radiation describes energy moving through space or matter in the form of electromagnetic waves or particles. Some radiation is familiar and sustaining, such as sunlight and warmth, while ionizing forms can alter atoms and damage living tissue. In poetry, radiation can hold this double meaning of nourishment and peril: a radiant face, a contaminated landscape, a signal crossing darkness. It gives intensity to images of exposure, inheritance, illumination, and unseen consequence.
Example
Example in poetry:
“Radiation from the hospital room glowed in the speaker’s imagination” can introduce the uneasy overlap of treatment and danger; A poet can describe sunlight as radiation to make a familiar warmth feel physically powerful; “The Geiger counter clicked through the radiation’s silence” uses sound to dramatize an otherwise invisible force; In a space poem, cosmic radiation can represent the hazard astronauts face beyond Earth’s protective atmosphere
Additional Notes
Radiation is not always dangerous: visible light and warmth are radiation. Ionizing radiation has enough energy to alter atoms, whereas radio waves and infrared are non-ionizing forms.
