Science Results for Everyone
Researchers measured radiation inside the space station and crew exposure in order to develop more reliable estimates of the radiation risk in low-Earth orbit. The project obtained experimental materials for assessing biologically significant human radiation dose during space flight. Results convincingly showed that using only thermo-luminescent detectors (which measure emitted visible light) give an absorbed dose reading with an error of up to 10 percent and an equivalent dose with an error of plus or minus 30 percent. This error can be reduced by using both thermo-luminescent and solid-state track detectors, which measure radiation based on tracks the particles etch in a solid material.
