Yields of hydroxyl radical and reducing species in tritiated water based on the radiolysis of tetranitromethane.
Yields of the nitroform anion produced in tetranitromethane aqueous solutions including tritiated water with and without isopropanol were measured. Yields of .OH and reducing species (e-aq + .OH) were calculated from the yields of the nitroform anion. The G values obtained for them were 3.8 and 2.5, respectively. The former was higher and the latter was lower than those for 60Co gamma-rays. Their beta/gamma ratio was 1.36 and 0.76, respectively. The beta/gamma ratio, 1.36, for .OH may be related to r.b.e. values higher than the one reported for 3H beta-rays.
