This book contains a useful compilation of material regarding physical and engineering aspects of ultraviolet radiation. Various sources of ultraviolet radiation are described, and the physical basis for their different characteristics is discussed in a readable fashion. There is an extensive discussion of the ultraviolet light of sunlight and the reasons for its diurnal, seasonal, and geographic variation. Transmission and reflection are treated at some length, and there is a discussion of devices for measuring ultraviolet radiation. All this is useful material, well presented from the point of view of the engineer.
The weakness of the book lies in its treatment of biological and medical problems, where it is not always up-to-date or complete, and, in places, is inaccurate. One serious difficulty lies in oversimplifications made to facilitate approximate quantitative estimates for engineering purposes, some of which may lead to wrong conclusions. An example is the attempt to calculate the
