Abstract
A scintillation counter comprises zinc sulphide dispersed in a resin or plastics material such as cellulose acetate and deposited on a solid plastics, such as cellulose acetate, or metallic support, the zinc sulphide particles having a diameter of from 1 to 5 microns and the thickness of the deposit being such that its optical density is from 0.30 to 0.35, corresponding to a thickness of from 0.01 to 0.04 mms. The zinc sulphide can be activated by silver. The zinc sulphide can be dispersed in a varnish comprising a solution of cellulose acetate before application to the support, the ratio of the weight of the dry material of the varnish to the weight of the zinc sulphide being from 5 to 15%. Other materials for the varnish can be silicone greases, synthetic rubber solutions, polymethyl-methacrylate solutions, polystyrene resin base varnishes, polyvinyl resin base varnishes, and heat-modified polyvinyl resin base varnishes. Materials for the support can be cellulose acetate (Registered Trade Mark "Rhodoid"), polymethylmethacrylate (Registered Trade Mark "Plexiglas"), "Plexigum" (Registered Trade Mark), polyvinyl resin, polyesters (Registered Trade Mark "Mylar"), polyethylene, and aluminium.
