Abstract

The systems most commonly used for low level GAMMA RADIATION SPECTROSCOPY in seawater, are based on NaI (Tl) detectors, which are characterized by high detection efficiency and low cost.137Cs is the most important radioactive contaminant, produced from the atmospheric bomb tests, discharges from nuclear reprocessing plants, leaking of concealed nuclear waste and in general of the sea (ocean). To select gamma ray of radiocaesium counting detector in the sea water near Bushehr nuclear power plant (B.N.P.P), MCNP.4C were used to simulate three different dimensions of (2inx2in (long x diameter), 3inx3in and 6in x3in) cylindrical NaI (Tl) detectors and in turn the volume of sea water, and chemical and physical characteristics of the sea water near the B.N.P.P and optimum fluxes was calculated.Response of detectors to gamma radiations by using MONTE CARLO CODE MCNP.4C for simulated condition was calculated. The obtained results showed that NaI (Tl) detector with 6in x3in dimension is a suitable detector for online radiocaesium monitoring in Bushehr sea water.
