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 populace and leading to Huitzilin gaining massive powers. (NA: The Left-Handed Hummingbird) The Solonians used thaesium radiation to cause the "mutations" that were part of their life cycle. (DW: The Mutants)

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 the highest radiation level in the galaxy of Mutter's Spiral. (DW: The Android Invasion)
• The Petrified Forest of Skaro had a high radiation level as a result of a past nuclear war between the Thals and the ancestors of the Daleks. (DW: The Daleks)
• The Doctor regenerated due to radiation exposure on Metebelis III. (DW: Planet of the Spiders)
• The Doctor regenerated due to radiation exposure, taking the place of Wilfred Mott. (DW: The End of Time)
