title: Yields of hydroxyl radical and reducing species in tritiated water based on the radiolysis of tetranitromethane.
abstract: 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.
