Delta Radiation is a type of radiation generally only seen from Anti-Matter explosions. It can however be produced artificially.
Delta Radiation is a sudden burst of EM radiation that covers all known bandwidth from Gamma Ray to Infrared. This wide spectrum cover makes it dangerous to many species, even some robotic races/bodies whose circuits may be fried.
It generally appears as bright light/laser since it also covers the visible spectrum.
- Delta Radiation comes from Star Trek
