VYNS film

Vyn-Eae<. [Syn. Prods.] Stearamide antiblocking agent for plastic films. 

In order to avoid the accumulation of electrical charges on the source mount in a An counter, the thin VYNS film thus prepared should be rendered electrically conducting by the vacuum deposition of gold or aluminum to both sides ( 15 gg/cm each side). 

The self-absorption values are very dependent on both the p-ray energy and source conditions, and are in the range from 1% to several tens %. In order to get reliable data with this technique, minimizing the foil- and self-absorptions is essential. The source preparation techniques are therefore of great importance. As materials for source support, a VYNS film (copolymer of vinyl chloride and vinyl acetate), whose thickness
