Attenuation Property of Wood and Fiber Reinforced …

1 · The attenuation capacities of some locally available wood and fiber reinforced polymer composite samples were evaluated in terms of relative attenuation factor (RAF), linear attenuation (µ), and mass-attenuation coefficients (µ m). Apparently, all the studied materials indicated a potential shielding property for both gamma and neutron radiation.
