Dose estimation using quartz OSL in the non-linear region of the growth curve.

abstract：:An important factor in calculation of quantities describing the radiation situation is the selection of a calculation code. In this article, the radiation situation for selected geometries with multilayer shields was judged. Calculations were carried out using deterministic code VISIPLAN and stochastic code MCNP5. Int...
