Additions of lead oxide to strontium-containing enamels have not improved their acid resistance. A powder spreader was developed which allows the remote and automatic deposition of uniform and reproducible enamel coatin gs on source-backing materials. An extrapolation chamber was constructed, but surface dose-rate measurements with it were not successful for the very-low-activity beta sources on hand. It will be useful for dose-rate determinations with the higher- activity sources which are to be prepared. Pre-irradiation hot styrene or comonomer dips show an increase in the grafting rate for the methacrylic acid- styrene system on polypropylene. A strong temperature dependence is shown for MAA-styrene radiation graft copolymerization on polypropylene. Major polypropylene fiber producers have expressed interest in samples of grafted dyeable polypropylene fabric which were prepared at RAl. Work is continuing on a design and cost estimate for a pilot-scale graft-copolymerization beta irradiator. (auth)
