Neutron and photon fluxes generated from the operation of fission reactors fuel cycle facilities are normally well attenuated with shielding ceiling walls.However, skyshine dose rates were observed at 1.5 -2 km away JCO criticality accident site Tokai-mura.In this study reactor neutron calculations Baikal-1 experiments have been performed TRIPOLI-4 Monte Carlo transport code.Baikal-1 carried out 300 kW RA research reactor.The 85 cm thick concrete plug in upper direction was removed during experiments.Various distances up to 1500 m considered for radiation measurements.To off code, both coupled neutron-photon so as include primary photons, neutrons, secondary photons contributions.TRIPOLI-4 perturbation on ground density hydrogen concentration contained composition also applied groundshine.
