Biological Effects of Ultraviolet Radiation

Except for the studies of partial cell irradiation by ultraviolet microbeams, most of the data concerning the biological effects of ultraviolet irradiation have been obtained in studies utilizing relatively simple and inexpensive apparatus. As more sophisticated instruments such as the microbeam combined with monochromatic light sources and the flying spot microscopes are perfected, even more critical biological analyses should be forthcoming. The few examples of the contributions of ultraviolet radiobiological studies to the analysis of complex biological problems briefly discussed in this paper serve only as indicators of the future progress which will result as these radiobiological techniques are applied to an even wider range of biological problems.
