مطالعه پرتوهای فرابنفش انتشار یافته از لامپ‏های فلورسنت فشرده متداول

Authors

Abstract:

Background and aims: Compact fluorescent lamps(CFLs) are low-pressure mercury vapor lamps, which are more useful than other light sources. Some studies reported the leakage of UV radiation from CFLs. The aim of this study was measuring of ultraviolet radiation from universal compact fluorescent lamps in Iran. Methods: In this study, measuring of UV radiation of 54 bulb compact fluorescent lamps from domestic and foreign companies with different brands and cover (Warm Light – Cool Light) were studied. UVA and UVB with Hagner-EC1 for UV-A and HAGNER photometer with UVB-Meter sensor probe were measured. Results: The results showed that the amount of UV radiation Increase with decreases distance and angle from nadir. Statistical test showed the electrical power had effect on UVA intensity radiation of UVA (r=0.36, P =0.008) and UVB (r=0.37 P =0.005). In addition, UVA lamps based on different light color (cover) had significant difference (P =0.000), But UVB based on cover differently had not significant difference (p>0.05). Mean matched values (emission 10 watts) UVA and UVB radiation between companies had significant difference (P<0.01).Conclusion: Exposure to UVA of studied CFLs at distances less than two meters are safe for working and social users, but exposure to UVB for less than 2 m for social users and 1 m for worker should be limited. Therefore it is necessary keep distances or using safe bulb lamps or safety glasses for near exposures.

ارزیابی پرتوهای فرابنفش لامپ‌های کم‌مصرف از نوع فلورسنت فشرده

Iranians are replacing traditional incandescent lamps with Compact Fluorescent Lamps (CFLs), because they use about a quarter of the power of incandescent lamps and their lifecycle is up to ten times longer. Government encourages public to use CFLs too, for saving energy and reducing carbon dioxide emissions. Small amounts of mercury are used in CFLs, released to the environment if they are bro...
