Studies of correction methods for influences from space environment on observation of radiation dose in space

摘要

Observation of radiation dose in space by using semiconductor devices is advantageous in terms of compactness, small power consumption, and structural simplicity. However, data sets obtained by these devices tend to have errors due to annealing effect and temperature variation, leading ambiguities in evaluations and models of space radiation environment used in spacecraft design. These errors can be briefly corrected by data processing. The correction makes temporal variation of radiation dose rate more clear and total radiation dose more accurate.
