Long-afterglow phosphors can be used in watch fingers, and also in safety applications, e.g., in exit signs, which still operate in the case of a current blackout. Other long-afterglow materials are e.g. ZnS Cu or SrS Bi. 

Unit equipment (self-contained battery packs with integral or remote lamps) provide the lowest initial cost for emergency egress lighting and exit signs but require considerable maintenance. 

Exit signs Exit signs are coated with a paint containing phosphors. These phosphors are activated by the radioisotope tritium (jH), produced by bombarding lithium-6 with neutrons to produce lithium-7. The lithium-7 then undergoes alpha decay to produce the tritium. Write balanced nuclear equations for both steps.

A white-on-red EXIT sign is illuminated on the rear wall of the chamber. Its obscuration by smoke accumulation during the test procedure is recorded. Starting from the flame application, the percent light absorbance is recorded at 15-s intervals or plotted by a recorder for 4 min (Fig. 4.3).
