Radiation
Radiation is energy sometimes produced by materials and sometimes by physical interactions, such as the contact of matter with anti-matter.
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 touch in early symptoms, progressing to a jelly like texture in later exposure. Upon death the body looses cohesion and collapses into 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)
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, 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.
