| Popis: | This communication provides a brief overview of an efficient, fast, and computationally inexpensive method for evaluating the contribution of prompt gamma rays to dose rate around shielded neutron guides. Parameterized probabilities for neutron absorption in the materials of the neutron guide coatings during reflection were implemented in McStas ray-tracing simulation software together with analytical formula and tabular data necessary for a numerical evaluation of a dose equivalent. This allows evaluating the dose rate beyond the lateral shielding upon simulation of the guide ray-tracing. |
