Radiation
Radiation is energy sometimes produced by materials and sometimes by physical interactions, such as the contact of matter with anti-matter.
Biological effects
Radiation is often harmful or fatal to most life and can cause mutations. Some organisms can withstand large amounts of radiation, such as the Foamasi (DW: The Leisure Hive), while others can actually absorb and regenerate with it, such as the Kastrians (DW: The Hand of Fear) or beings such as the Daleks on Skaro, whose evolution led (at various points) to them becoming dependent on a constant supply of radiation. (DW: The Daleks) Similarly an Exxilon fuel pod was left in ancient Earth Incan civilisation causing mutations in the populous and leading to Huitzilin gaining massive powers.

Radioactive locations
- Argolis had a radioactive atmosphere as a result of a nuclear war. (DW: The Leisure Hive)
- On the planet Janus Prime the radiation on the planet made its sand glow blue, it also destroyed a (human) body's lipids, making skin sticky to the touch until it turned into jelly-like in texture. Upon death, the body lost cohesion and collapsed into a porridge=like substance. (EDA: The Janus Conjunction)
- Messaline had a relatively high level of radiation, this was however eradicated via terraforming methods. (DW: The Doctor's Daughter)
- Oseidon had a high radiation level. (DW: The Android Invasion)
- The Petrified Forest of Skaro had a high radiation level. (DW: The Daleks)
