Self-luminous compounds were prepared by activating them with beta sources. A salt containing a radioisotope such as P/sup 32/, S/sup 35/, or Sr/ sup 90/--Y/sup 90/ was mixed with an inorganic ph osphor, and the relative efficiency of the conversion of beta ray energy into light quanta, i.e., the ratio of the emitted light intensity to the beta counting rate of the sample was determined. A ZnS-type phosphor with a long afterglow was the most efficient, but the level of brightness was as low as the order of 1 mu L/mc. The effects of the carrier concentration up to 5% and the specific radioactivity on the efficiency were not excessive. Experimental data are graphed. (OID)
