The effect of NaI(Tl)crystals on typical nuclides in nuclear wastewater γ MC simulation of energy spectrum response
This paper simulates the effect of NaI(Tl)crystal detector on nuclides 137Cs,134Cs,and 60Co in nuclear wastewater using Monte Carlo method(MC)γ Spectral response.The simulated data were combined with the standard values of nuclide concentrations in seawater of China and WHO for Gaussian broadening fitting.The results indicate that NaI(Tl)crystal detector can distinguish most of the energy peaks of the gamma spectrum emitted by these three nuclides.The change of nuclide concentration will also lead to great changes in the energy response curve.
