In George Romero’s 1968 classic, Night of the Living Dead, the zombie sickness is created by radiation from a fallen space satellite. Now forensic pathologist and ZRS member, Peter Cummings, has taken a hard scientific look at this possibility playing out in the real world.
Cummings has done extensive research for NASA on the effects of radiation on astronauts. He finds that not only could specific types of space radiation cause disturbing changes to the brain, it may also explain why zombies decay at a much slower rate than human corpses.
Because radiation can kill cells it’s used as a method of sterilization. Currently, radiation is used to kill micro-organisms on surgical equipment and food. This may explain why the zombie may decompose at a slower rate than the typical corpse.
Though Romero’s zombies differ from most popular depictions because they don’t transmit their sickness through bite, the radiation model he created does seem as realistic as more common depictions. It also answers some nagging questions about the zombie lifespan that other infection sources can’t.
