Description

The paper use MCNP5 procedures to build the TGS device model, it studies the effect of distance between the collimators to the detection efficiency by adjusting the detector front tablet, accounting several Nuclear Decommissioning substances frequently encountered. The simulation uses 60Co as the source and uses the distance step of 0.5 cm, and the results shows that the optimal distance is 3 to 3.5 cm. (authors)
