ABSTRACT

The mechanism of the inverse oxygen effect in the irreversible radiation-induced chemical alterations in protoporphyrin in sulfuric acid solution was investigated. The decrease of the molecular decay yield was shown to associate with the ability of oxygen to exclude H atoms from the radiation reactions and to inhibit the development of the protoporphyrin transformation chain process.
