ExMod/ModernSolarResistance

Radiation-Resisting Meditation
Cost: 4 motes
Duration: One Scene
Type: Reflexive
Minimum Resistance: 3
Minimum Essence: 2
Prerequisite Charms: None

The Solar Exalted bring order to the universe, and the energies of decay can do naught to harm them. This charm adds the character's stamina in automatic successes to the Stamina+Resistance roll to resist a dose of radiation. This charm may be invoked after recieving the dose or beforehand. This is an effect of essence strengthening th Exalt's body - were she x-rayed, the radiation would still form an image on the film.

Immunity to Everything Technique

As normal, but requires Radiation-Resisting Meditation as a prerequisite and allows the character to be unaffected by radiation. This is a perfect defense against radiation - for the duration, the charcter could be exposed the radiation of an atomic bomb with no harmful effects.

Comments

Thought you might want to send a Solar into a radioactive waste dump or something similar without them having to don bulky protective gear. - OmegaPaladin

One note: Rather than adding a prerequisite, perhaps you could add the 2E-style text of "If a character who knows this charm activates Immunity to Everything Technique, that charm will also perfectly protect the Exalt from radiation, just as it currently protects from illness and poisons" -- GreenLantern, thinking there's no need to move something up the tree.
