The Do/ collaboration is building 4608 scintillation counters to upgrade forward muon system for the next Fermilab Collider run. Each counter consists of 12.7 mm thick scintillator plate with two WLS bars along two sides for the light collection. With average 10 2 photoelectrons from mip particle the counters provide time resolution below 1ns and have good energy resolution. Results of Bicron 404A scintillator and Kumarin 30 WLS aging under irradiation up to 3Mrad are presented. With specially designed magnetic shielding counters can operate in magnetic filed up to 500G.
