Measurement of the intensity of Solar Ultraviolet A Radiation at Date Harvest Time in Groves around Jiroft City

Back ground and Aim: Solar Ultraviolet radiation type A leads to many skin disease. As workers such as peasants and other ones whose job is in uncovered places has exposure with this radious, in this study we aimed at measourment of the intensity of cosmic UV type A in palm-groves at wich workers .gather date in the vicinity of Jiroft Materials and Method: This is a descryptive-analitical cross-sectional study through wich data were gathered from six different regions of Jiroft suburbs comprise of AnbarAbad, Qaleh Ganj, Fariab, Ji roft, Roodbar and Blook randomly. According to the date harvest time, we did our study through July and September 2017. The Hagner Digital Radiometer EC1 UV-A instrument was used to evaluate the intensity of UV radiation and then data was compared with standard tresholds advised by ACGIH. Moreover, altitude from sea level and latitude, elements which may have influence on UV radiation,.were analysed Results: Our study showed that the average of UV radiation in Jiroft palm-groves is around 23.6 w/m2 . Moreover, besed on our findings all UV radiations exceed permissible range announced by ACGIH during all work-hours except between 6-7 AM which is job start time table2 . However there was no .significant correlation between UV-A and lattitude or height from sea level Conclusion: The range of UV-A, workers have exposure with during date-harvest is higher than permissible range advised by ACGIH
