THE ROENTGEN RADIATION OF PAPILLOMA VIRUS (SHOPE)

Abstract

Virus-induced papillomas (Shope) on domestic rabbits are susceptible to Roentgen rays. The dosage which uniformly brings about their complete and permanent disappearance has been found to be 3600 r (200 kilovolts), whether this dose be administered at one time or fractionally. 60 per cent of the tumors are cured when irradiated with 3000 r.
