The quantitative study of the biological action of radiation is generally considered difficult in the case of skin erythema, and results obtained by different workers using ultra-violet radiation to produce the erythema are often contradictory. Much quantitative work has been done to ascertain how far any biological action runs parallel with the amount of physical stimulus, but this has usually been done on plants, histological sections of tumours, cultures, albumen, etc., and using more ofter γ-rays and X-rays than the longer ultra-violet rays. The present paper is preliminary to further study, and is concerned with the precautions necessary to obtain reliable and consistent measurements of the amount of skin erythema resulting from exposure to ultra-violet rays.
