Radiation-induced C¹⁴-formate oxidation was studied under a variety of experimental conditions. Since the C¹⁴O₂ yield can be increased by traces of catalase, an enzymatic and a nonenzymatic component may be distinguished. Either component of C¹⁴O₂ formation is influenced by temperature, pH, gas phase, and irradiation techniques in a different manner. Highest yields are observed in N₂O phase (G ₊CO₂ = 7 to 8). Whereas an increasing effect of catalase is oliserved in O₂ and N₂O, there is none in N₂. A small but distinct dose-rate dependency exists between 35 and 400 r/min (250 kv x rays).
