摘要：

A series of high dose rate (20 kGy/hr) and low dose rate (<10 Gy/hr) irradiations of a large sample of plastic scintillating fibers (1 mm phi, 150 cm length) has been completed. Measurements of the transmission characteristics of the fibers have been completed and the results are presented in this report. Measurements of the loss to intrinsic scintillation output will be completed at a later date. The transmission measurements show striking features: (1) those fibers irradiated slowly iii air (i.e., in the presence of oxygen) suffer the greatest level of damage, while (2) the fibers irradiated rapidly, and then allowed to recover, display the least amount of damage, and (3) fibers irradiated slowly in argon display a level of damage intermediate between the other two. One fiber, the green-emitting SCSF-Y8, is the only exception, and shows no difference in the level of damage observed in the three modes of irradiation.
