个体紫外线暴露剂量与环境紫外线剂量的关系

Study on relationship between presonal exposure of ultraviolet radiation and ambient solar UVR

目的 了解个体紫外线暴露剂量与环境紫外线剂量的关系。方法 采用紫外线个体监测仪在秋季对沈阳市小学生和大学生进行紫外线剂量的测定 ,同时开展环境紫外线剂量的监测。结果 学生个体暴露量的日间分布是由户外活动时间决定 ,与作息时间关系密切。学生日平均暴露量只占环境剂量的 1%～ 3 %。结论 小学生的紫外线暴露量和与环境剂量的比都明显高于大学生。

Objective To investigate the relationship between personal exposure of ultraviolet radiation and ambient solar UVR.Methods Both doses were monitored in Autumn in Shenyang by using spectral sensitivity of solar UV sensor.Results The distribution of personal exposure in a day dependented upon outdoor time and rest time.The mean dose of a person received UV was 1%-3% of ambient solar ultraviolet radiation dose.Conclusion The rate and personal dose receiving UV of pupil were higher than those of collegian.There was significant difference among ambient solar ultraviolet radiation doses monitored by various way.
