National Lamp Works

The authors are grateful for the contribution of D. D. Davis of the National Bureau of Standards, who provided valuable assistance in the design and construction of the photolysis lamps used. The authors also thank A. K. Bhattacharya, who accomplished some of the experimental measurements reported here. This work was carried out during the tenure of a National Academy of Sciences-OAR Postdoctoral Research Associateship awarded to B. M. Hughes for 1967-68. 

The following text provides details of an actinometric procedure for monitoring exposure to a near-UV fluorescent lamp (based on work done by the FDA/National Institute of Standards and Technology study). For other light sources and actinometric systems, the same approach may be used, but each actinometric system should be calibrated for the light source used.
