The present application relates to a kind of gamma spectrum based on
branch fusion network's spectrum and
dose prediction method, using Monte Carlo method to construct the model consistent with actual detection
system, obtain the single-energy
response spectrum under different energy gamma
radiation, and establish the response relationship between
energy spectrum and air absorption
dose;Through the construction of
detector response matrix and
energy spectrum superposition principle, generate multi-energy mixed
energy spectrum and corresponding
dose label data set, while covering
point source and body source
radiation scene.Based on the
data set, establish the spectrum model based on residual network, realize the inversion reconstruction of each
energy component in mixed energy spectrum, to construct multi-
branch feature fusion neural network to realize the nonlinear mapping from spectrum to
dose rate.Model is based on homologous data progressive drive, output energy spectrum structure information is used to output dose information after the information, realize the energy composition and
dose level collaborative representation of
radiation field.It avoids complex inversion
algorithm, improves the applicability and stability of model in complex
radiation field.
