Science Results for Everyone
An astronaut’s skin absorbs as much as 20 times more space radiation than do the organs deep inside the body. So what is the actual dose an individual receives? Based on a determination that radiation dose declines steeply in the first 8 mm of skin, researchers calculated an average dose rate for each critical organ. The calculated skin dose rate of the outermost 3 mm, about 1 mGy/day, is by far the highest, followed by that for the eye. Dose rates for other organs, with the exception of breast and salivary glands, range from 0.2 to 0.3 mGy/day. These depth-dose distribution characteristics can serve as benchmarks for future mission medical planning.

Results/More Information

The relationships between the skin and organ absorbed doses obtained in such an exposure show a steep gradient between the doses in the uppermost layer of the skin and the deep organs with a ratio close to 20. This decrease due to the body self-shielding and a concomitant increase of the radiation quality factor by 1.7 highlight the complexities of an adequate dosimetry of space radiation. The figure to the left shows the interpolated depth distribution of dose rates including the skin measurement. It highlights the very steep decline within the first 8 mm by a factor of about ten. From this depth-dose distribution, an average organ dose rate was determined for each critical organ as the average of the dose rates in those volume elements that were assigned to it in the voxel model. The corresponding results are given in Table associated with the Figure. The calculated skin dose rate represents an average of the outermost 3 mm. With about 1 mGy/day, it is by far the highest, followed by the dose rate in the eye. With the exception of the breast and the salivary glands, the dose rates for the other organs are in the range from 0.2 to 0.3 mGy/day.The depth-dose distributions established by Matroshka serve as benchmarks for space radiation models and radiation transport calculations that are needed for mission planning.
