— Simple measurement of germicidal (2537 Å) u.v. in a geometrically complex system is described. The radiant energy incident upon thin egg white films in a rapidly spinning centrifuge was integrated over time periods with NBS light‐sensitive paper. The radiant killing of contaminant Salmonella was found to be one microorganism per 10 11 quanta absorbed by the medium.
