Title: Medical gamma ray source with uranium shielding - has protective coating resisting attack of shielding by nitrous gases
Inventor: HAUBOLD HELMUTH ING GRAD
IPC: G21F1/12
Filed: 1974-09-27
Abstract: A radition shield for surrounding a gamma ray source is made of uranium; the uranium surface is protected by a coating which resists attack from nitrous gases. Pref. coatings are: a quartz layer applied over the nicket coating of the uranium; a gold layer applied over the nickel coating; or aluminium, esp. eloxadised aluminium.

Its immediate cause is nitrous gases produced by radiolysis. Quartz must be applied under vacuum. Gold is applied electrolytically. Aluminium is also applied electrolytically, omitting the nickel coating.
