Resumo

Modeling of absorption capabilities of different plastics, including those with different content of boron nitride for ABS-plastic was performed. Modeling was carried out using the PHITS software package. The paper compares the results of modeling the absorption capacity of plastic with experimental data. The case of practical application of ABS-plastic as neutron-absorbing shutters of a diaphragm is considered.
