Abstract
The results of the radiolysis of aqueous solutions or thiamine (vitami n B-1) are presented. The yields for decomposition or thiamine and the production of radiolytic products were determined. The G values decre ase as the dose increases. Some radiolytic products were identified. D ecomposition of thiamine was slightly dependent oil the presence of ox ygen and oil the pH of the solution. At pH 4.4, with a concentration o f 2.5 x 10(-4) mol L-1 of thiamine in an oxygen free aqueous solution, the G(0) value for decomposition is 5.0.
