|
| The development of a radiation shield is utmost important to attenuate the intensity of radiation reaching out to the outer world. Such analyses involve calculations of buildup factors which are central to every shield design to be carried out. In particular, to justify the practical shielding necessities, one must investigate for multiple layered shield designs. For buildup factors, the Taylor’s approximation has been broadly customized through numerous studies for single-layer shields and has been found sufficiently precise to provide buildup information in the compounds and the elements tested for. In this reference and connection to our previous study, here the author attempts a detailed investigation of Taylor’s approximation through Program BUF toolkit for composite shields extending up to five-layered shields. Interestingly, the developed toolkit proves accurate enough to calculate buildup data for a composite shield design. Numerical calculations are carried out using BUF toolkit taking basis of Taylor’s fitting formula. The validity of the developed source code is examined by comparing its results with the buildup data of composite shields available in literature. The results are able to reproduce the existing data, wherever possible, in both single- and composite shields extending to five-layer designs. In this paper, except for four-layered shields where no experimental data is available for comparison, the other results of the present work assuming composite shields up to five layers are directly made to compare with the corresponding simulation data available. Noticeably, the BUF results are seen to show good agreement with the experimental results. The source code BUF calculates buildup factor data in the energy range of 0.5 MeV-10 MeV for shields having effective atomic number lying between 10 and 92. |
