IMPROVEMENTS IN SELF-LUMINOUS LIGHT SOURCES
Patent

OSTI ID:4058617
A self-luminous light source is designed which provides a great increase in visible light intensity with ample effective life and safe radiation levels. This source is a body formed with a cavity in which a phosphor layer is disposed and over which a transparent or translucent plate is disposed to form a shallow closed chamber. The chamber is evacuated and then filled with krypton-85 or tritium to a pressure less thmn atomospheric but sufficient to excite the phosphor to luminescence. The plate is made out of material which is resistant to darkening by radiation and which serves as radiation shielding. Applications of this light source as a sign or marker and as a two-way lantern are discussed. (D.L.C.)
