Query: Extruded Plastic Scintillation Detectors   As a way to lower the cost of plastic scintillation detectors, commercially
available polystyrene pellets have been used in the production of scintillating
materials that can be extruded into different profiles. The selection of raw
materials is discussed. Two techniques to add wavelength shifting dopants to
polystyrene pellets and to extrude plastic scintillating strips are described.
Data on light yield and transmittance measurements are presented.
