Abstract
Copper activated zinc sulphide phosphor was coated with tritiated polystyrene to give self-sustained light sources. The stability of the zinc sulphide phosphor coated with polystyrene was studied. It is suggested that the drastic reduction in light output over a period of two years may be due to the phosphor damage rather than loss of radioactivity.
