Radiation Release (Heishiro)

Radiation Release (放遁 Hōton; Viz "Radiation Style") is an advanced chakra nature kekkei genkai made up of techniques that combine fire and yang-based chakra to create different forms of radiation.

The user manipulates fire-based chakra and empowers it using the life energy of Yang-based chakra. This creates a highly exothermic process capable of releasing various types of radiation.

Radiation Release is used to produce extreme heat, as well as simply producing ionizing radiation, potentially causing varying degrees of radiation poisoning whilst leaving the user nigh immune to the same.

Known Users
Ishin Kibō: Ishin has been known to use Radiation Release both to produce unique techniques that take advantage of the immensely damaging properties of ionizing radiation as well as using the nature to seemingly "enhance" run of the mill Fire Release techniques with deadly efficiency. Ishin is known to be capable of killing within ever touching his target in this way producing enough ionizing radiation to destroy a body at a cellular level, although as he must be relatively close (within 50 feet) to do so and the potential for high levels of collateral damage as the irradiated target moves about means this method of killing is rarely employed.
