Conclusions

  1. 1.

    Two groups of radicals resulting from the interaction of the oxidizing component of the water radiolysis with the phosphate ion have been identified in aqueous H3PO4 and NaH2PO4 which had been irradiated at 77°K. The photolytic properties of these radicals have been studied.

  2. 2.

    Radical anions and cations are the primary products from the radiolysis of azo bases in phosphoric acid solutions. The molar absorption coefficients of these radicals have been determined.

  3. 3.

    Radiochemical yields of radicals have been determined in phosphoric acid solutions of various compounds. The yield of phosphate radicals is twice as high in H3PO4, solutions containing nitrate ions as in pure H3PO4. Radiosensitization effects are observed here.
