Research on Solar-UV Individual Exposure of Pupils in Shenyang / 环境与健康杂志

ABSTRACT

Objective To explore individual exposure to solar-UV radiation of pupils in Shenyang in four seasons. Methods Personal exposure to solar-UV radiation of pupils in Shenyang in four seasons was measured with ultraviolet radiation individual monitors and at the same time UV intensity in environment was detected also. Results Results of the present paper showed that higher UV exposure dosage of the pupils had been determined in spring and autumn, lower dosage had been determined in winter and summer respectively. The accumulative UV exposure time of pupils showed lower levels in winter compared with those in spring, summer and autumn. Higher UV exposure dosage and exposure time had been determined in class day than those in break day. The annual mean of daily UV exposure dosage and exposure time presented higer levels at noon. The mean of daily exposure of pupils was less than 8 percent of environmental UV intensity. Conclusion The distribution of UV exposure of pupils in daytime is corresponded with time spent outdoors. Individual differences are mostly caused by personal behavior. Seasons may affect personal UV radiation exposure. The UV exposure received by individuals only take a little part of total environmental UV radiation.
