Neutron exposures in human cells: bystander effect and relative biological effectiveness. [PDF]

PLoS ONE, 2014
Bystander effects have been observed repeatedly in mammalian cells following photon and alpha particle irradiation. However, few studies have been performed to investigate bystander effects arising from neutron irradiation. Here we asked whether neutrons
