Notes:
Irradiation dose rates and complete depth - dose curves in polyethylene have been directly determined with a silicon solar cell. In this manner, an average dose rate of 0.297 Mrad/sec. per incident μamp./cm.2 for 1 m.e.v. electrons in 120-mil thick Marlex polyethylene was measured. The corresponding dose rate ascertained by ferrous sulfate dosimetry is 0.260 Mrad/sec. This difference is in the expected direction and may arise from differences in backscatter between polyethylene and silicon. The facility of the solar cell measurement and the complete definition of irradiation dose as a function of absorber thickness commend the device for general application in irradiation dosimetry.
