Calculation of gamma-ray exposure buildup factor based on backpropagation neural network

作者：

Highlights：

• The BPNN method is used to calculate the gamma-ray exposure buildup factor.

• The results are consistent with the ANSI standard and better than G-P fitting formula.

• Compared to MCNP method, the BPNN method is efficient and accurate.
