Reactor channel characterization is commonly performed by irradiation of bare and cadmium-covered "fluence rate-monitors", avoiding as much as possible the use of irradiation vials/capsules and spacers for positioning the monitors inside the channel. However, in routine k0-Neutron Activation Analysis is generally necessary to pack the samples in polyethylene vials prior to irradiation. This work aims at studying the impact of polyethylene vials on the f (thermal-to-epithermal flux ratio) and alpha (epithermal flux distribution) parameters through the bare, cadmium-covered and Cadmium-ratio methods. The accuracy of each method will be discussed.
