This study describes the effects of the detector-collimator on the gamma-ray response function for NaI(Tl) detectors with 2 x2 , 3 x3 and 5 x5 dimensions. In present study we have used five different detector-collimators and three gamma ray...

Due to the necessity of using low background NaI detector in sensitive and accurate measurements, study on the response function variations in different conditions is very important. These types of detectors have different ...

The importance of reducing the activation of NaI(Tl) detectors when used to detect g-rays in the presence of an intense neutron environment is discussed. Monte-Carlo calculations are used to design proper shielding for these NaI(Tl) detectors...

a suitable neutron shield for NaI detector in order to prevent the activation of NaI (Tl) and a proper g-shield to attenuate the high-rate 4.438MeV g-ray, 241Am–Be g-ray component....

Response functions of a 3×3 in. NaI detector, which is mainly used in PGNAA

applications, have been calculated by using MCNP-4C code. Calculated results are compared

with measured data by using standard γ-ray ...

The well-known MCNP code was used to simulate the NaI(Tl) Detector Response Function (DRF) with 2x2, 3x3 and 5x5 crystal dimensions for gamma rays from 241Am, 137Cs and 60Co sources. Then a code named RNAIGA has been slightly written by us which...

The gamma ray spectrum resolution from a 241Am–Be source-based prompt gamma ray activation analysis set-up has been observed to increase in the energy region of interest with enclosing the NaI detector in a proper neutron ...

was used. Thermal neutron flux determination in

paraffin phantom by counting the emitted rays of indium foils with two different detectors (Geiger–

Muller counter and NaI(Tl)) was the aim of this project. The relative differences...
