[Investigations on secondary emission of metallic implant materials Ti and Ta following radiation]. / Untersuchungen zur Sekundäremission der metallischen Implantatwerkstoffe Titan und Tantal bei Bestrahlung.

ABSTRACT

Two implant materials, titanium and tantalum, were investigated for their electron emission in response to therapeutic tumor irradiation and were compared, in this context, to a substance equivalent to bone. The reaction of titanium was found to be similar to that of bone, whereas substantive increase in radiation was caused by tantalum which, consequently, should be removed from the radiation field.
