Examples of induced radioactivity

Induced radioactivity is the ability to emit radiation and/or induce radioactive properties into objects and people.

Characters

• Ted Sprague is the only character known to have this ability.
• Peter Petrelli has absorbed this ability.

Limits

Ted has limited control over his ability to emit radiation. When agitated, he appears to emit radiation unintentionally. This radiation can be harmful to people in his vicinity. His control has improved with practice, and he seems to be able to emit radiation on purpose, but he apparently cannot consistently prevent himself from emitting radiation, especially if angry or injured.

Ted can apparently emit a broad spectrum of electromagnetic radiation, although he has only a limited understanding of the physics involved. He can not choose specifically whether to emit microwaves or gamma rays, but he can choose whether to radiate "hot" energy or "bright" energy. Whether he can generate particle radiation (alpha rays or beta rays) is unknown.

At close range, Ted can produce enough radiation to bring a glass of water to a boil or melt a brass door lock in just a few seconds. His uncontrolled emissions can set fire to common construction materials from several meters away. He is also capable of emitting an electromagnetic pulse strong enough to disable electronics throughout a large building.

Ted appears to be unharmed by his own radioactive emissions. He has caused the deaths of others (reducing people to skeletal remains) during at least two escapes, but never appeared affected himself. Whether this immunity applies to radiation from other sources is unknown.

Notes
