Introduction: Energy saving is an important item considering environme-nttal protection, economy and science and technology. Hence, one way of energy saving is using compact fluorescent lamps. In these lamps, ultraviolet radiat-ion is generated due to the nature of produce light. Until now, no study has investigated the proper distance to these lamps in Iran. Therefore, the present study aimed to evaluate the safe distance in facing UV rays of compact fluorescent lamps.
Materials & Methods: This experimental study was conducted on 16 compact fluo-rescent lamps (four different brands) in 8 different watts. Measurement was done in 200,150,100,50,25 and 10cm distance and 0,100,200,500,750,1000,1500 and 2000 hours from work time and in zero angles ultraviolet radiation was measured in three fields including UVA, UVB and UVC. The information was analyzed usi-ng SPSS 20 software through one-way ANOVA test.
 Findings: ANOVA test showed that there was a statistically significant relationship between the intensity of ultraviolet radi-ation at different distances (P<0.05). Also, ANOVA test was done to compare theint-ensity of ultraviolet radiation at different time and results showed that there was not a significant difference between different times in terms of intensity of ultraviolet radiation(P>0.05). Discussion & Conclusion: In 10cm dis-tance, the intensity of UVA radiation in two lamps (45 and 60 watts) was more than the occupational exposure limits bet-ween eight lamps and in 25cm and more distances, intensity of UVA radiation rea-ched less than the occupational exposure limits. Intensity of UVB radiation among most lamps in 10, 25 and 50 cm distances was more than the occupational exposure limits.
