ROENTGEN DOSAGE IN DERMATOLOGY EXPRESSED IN INTERNATIONAL ROENTGENS

ROENTGEN DOSAGE IN DERMATOLOGY EXPRESSED IN INTERNATIONAL ROENTGENS Abstract In a previous communication before this section we1 stated that the erythema dose for unfiltered radiation with 100 kilovolts was 300 roentgens. In the present communication we shall give the roentgen equivalents experimentally obtained for erythema doses for filtered radiations commonly used in dermatology. The majority of roentgenologists use between 550 and 700 r as the erythema dose with filtered high voltage radiations. The German roentgenologists, according to Küstner,2 use 551 r plus or minus 15 per cent for the erythema dose of filtered radiations. At the Cleveland Clinic 600 r is required to produce erythema with heavily filtered roentgen rays. Pfahler3 gave 650 and 700 r for an erythema, while Failla4 stated that 600 r was required to produce redness with heavily filtered radiations. With 4 mm. of aluminum and 127 kilovolts, Widmann5 used 600 r as the erythema dose. The different investigators were References 1. MacKee, G. M., and Cipollaro, A.

Abstract

Abstract In a previous communication before this section we1 stated that the erythema dose for unfiltered radiation with 100 kilovolts was 300 roentgens. In the present communication we shall give the roentgen equivalents experimentally obtained for erythema doses for filtered radiations commonly used in dermatology. The majority of roentgenologists use between 550 and 700 r as the erythema dose with filtered high voltage radiations. The German roentgenologists, according to Küstner,2 use 551 r plus or minus 15 per cent for the erythema dose of filtered radiations. At the Cleveland Clinic 600 r is required to produce erythema with heavily filtered roentgen rays. Pfahler3 gave 650 and 700 r for an erythema, while Failla4 stated that 600 r was required to produce redness with heavily filtered radiations. With 4 mm. of aluminum and 127 kilovolts, Widmann5 used 600 r as the erythema dose. The different investigators were References 1. MacKee, G. M., and Cipollaro, A.
