This system can instantly contain and prevent chemical, beam, and psionic weapons from penetrating or being used inside a TARDIS 's Control Rooms. Depending on how you look at it, people within a TARDIS's Relative Dimensional Stabilizer field don't exist in the Normal Space anymore. It is this that allows Temporal Grace circuits to work. A TARDIS can even flood its interior with Zero Particles to prevent anti-matter reactions. It should be noted that Zero Particles cause organic cell damage. The field is unable to affect the Master's Tissue Compression Eliminator because it works on the same principles as the dimensional stabilizers. A TARDIS's Emergency Procedures automatically try to divert any large explosion or energy release into its Eye of Harmony. While it can handle a cold fusion explosion a fission bomb set off inside the TARDIS will destroy the interior.
