J78_ CHAPTER 10 1948 Guide substantial number of physicians, bacteriologists,' aerobiologists, physi cists, public health workers, engineers and hospital personnel.-' Some data are available on the types and quantities of bacteria found in a variety of occupied and unoccupied spaces, but it is not possible at present to use-this information as a conclusive index of the potential health hazard of a given environment.' The reported number of airborne organisms may vary from 1 to 1000 per cubic foot of air, influenced some what by the method of testing 32.. Many are attached to the dust particles which are also present in the air. Where' it seems advisable or desirable to control the bacterial content of rooms, public conveyances or buildings, highly effective methods are available (see Chapter 13), and their extended use may do much to assist the workers in this field in accumulating the necessary mass of evidence that will decide the practical value of air sterilization for the control of communicable disease. It is now well.established that ultraviolet radia tion is commercially feasible for the protection or preservation of phar maceuticals, cosmetics, and food products.
