Monte Carlo Calculation Using Point-throughput Approach To The Research And Application Of Small Regional Counts

The paper discussed the problem of count in a small region, which was situated in a great system, and it introduced a special scheme of calculation for flux of cell or surface and current of surface.In some cases, the size of detector is so smaller than the size of the whole system that the direct simulating method can't figure out a well result. Basing on the MCNP software, the author solved the matter by calculating the value of point to replacing the value of cell or surface. The research searched out a new means to solve similar matters.By using the studying result, the author programmed the Gamma code, with the interface of window, which can simulate the course that a y-detector measures the radioactivity in soil and calculate the dose ratio and the chart of energy deposition.
