Backgrounds and Objectives: As industries are developed, human uses of the energy in the huge scale and release the loss  energy in the form of electromagnetic radiation such as infrared into the environment, that it could affect on the man health. According to the available standards, if the IR-A could be controlled and consequently health of workers could be provided, it would reduce the total industrial expenses.
Materials and Methods: To control this radiation, it is necessary to measure it and compare the results with the available standards. Hence, in this study, we try to  measure this radiation in a unit of industy. For this porpuse the unit of steel company that settled in southeast of ahvaz is selected.
Results: The determinations were done every month during one year in all selected units. These results are compared with the available standards, and finally the differences are statistically evaluated by some suitable statistical methods. For measuring the dispersal of ray in the diffrent height. bat hard data compared with ACGIH standard and SPSS software is used for changing Radiation.
Conclusion:  The  average amount of IR-A  at  this  industrial  unit  is  1.18 mW/cm2  which  is more than the standard value in such industries ,and based on our fouding the natural solar source of this radiation increases such effects in out-door work places.
