Evaluation of tritium and Carbon-14 radioactivity in primary loop of Tehran Research Reactor (TRR)

The purpose of this paper is evaluation of tritium and carbon-14 radioactivity and concentration in Tehran Research Reactor. Carbon-14 and tritium are radioisotopes produced as a by-product or special product in various nuclear reactor systems. Owing to their relatively long half-lives, high residence time in the environment, high isotopic exchange rate and ease of assimilation into living matter, it is necessary to control their production at nuclear facilities. In order to evaluate variation of C-14 and tritium in pool water of Tehran Research Reactor, four water samples were taken on a different dates from 2010-08-17 to 2010-11-21. For confirmation of their presence and some other gamma emitter radioisotopes α, β and γ spectroscopies performed on the mentioned samples.
