An Investigation of Zinc and Selenium Status on the Dark Adaptation of Radar Operators / 第三军医大学学报

ABSTRACT

This investigation shows the difference of Zu and Se status between the radar operators and non-operators. The results reveal that plasma Zn and Se contents of radar operators are significantly lower than those of the non-operators, but no statistical significance in hair.It is very likely that the plasma Zn and Se reflect recent status, because during training period the radar operators work more than 4h / day in the low illumination chamber. It suggests that the RDA of Zn and Se of radar operators should be increased in order to improve dark adaptation.
