Work in ultraviolet radiation.
At 51 departments where work is being done in ultraviolet radiation for sterilization purposes (sterilamps), the light intensity was measured at 254 nm and at 300-400nm. A limit of 0.25 microW/cm2 at 254 nm has been set. In several of the workplaces this limit was exceeded without any decrease in the number of colony forming units, according to the 940 settling rate counts made. The conclusion is that the use of UV radiation as an adjuvant to several other sterility measures has no effect, even when the limit is exceeded by 700%. It is advisable to use special working tables at which the person is not exposed directly to UV radiation.
