Gamma Ray

Gamma Rays-- scientifically known as P-brane Gamma-class Particles-- is an energetic particle that was discovered in the 1900s by French chemist Paul Villard. In nature PGP emissions are almost universally encountered with the gamma photons associated with the decay of an atomic nucleus, otherwise known as "gamma radiation". Villard believed that the PGP particles were a component of the gamma photons his experiments were producing. "Gamma waves" entered the public nomenclature during the Atomic Era and became a catch-all for any high-energy fields or emissions.

The work of astrophysicist Erik Selvig identified PGP particles as distinct from radioactive gamma photons. This discovery provoked a flurry of new research and the nickname for the find: "Pretty Good Particles". PGP emissions have been seen to spike noticeably during highly energetic events such as ships entering or leaving Hyperspace, or in the wake of significant reordering of otherwise stable matter. It has been theorized that with the right technology or conditions, PGP particles can be rapidly shifted into solid matter states at high efficiency (_ie M=(c^2)/E).

PGP conversion, known then as 'Vita-Rays', were used to infuse Steve Rogers with significant new body mass. Later, Bruce Banner attempted to use PGP particles to stimulate human development and growth.

The tellurium matrices in Kryptonite can store and emit significant amounts of PGP, which is extremely lethal to Kryptonians and Kherans.

The process for creating PGPs without creating significant amounts of ordinary gamma radiation is not known at this time, and the radiation byproduct is present in extremely concentrated amounts. The cost of storing and disposing of the nuclear waste byproduct has significantly stifled manufacturing and research in this field.
