The neutron absorbed dose was obtained by using the freqency mean lineal energy.Results show good agreement with measurements with the activation method using gold foil. This study demonstrated how microdosimetric parameters cahnge in radiation quality as a function of heaby water depth.}, pages = {383--385}, title = {Microdosimetry of epthermal neutron field at the Kyoto University Reactor.}, volume = {99}, year = {2002} }
