Assuming that the watch employed 2 mCi of tritium in paint, and that the watch was worn 16 hours per day, the average dose to the 10 cm2 of skin in contact with the watch was calculated to be 200 mrem. The greater the number of alpha or beta particles striking the crystals, and the greater the energy deposited in them, the brighter the light. The Pm-147, mixed together with ZnS in a polymer paint, is either an insoluble oxide or is incorporated into ceramic microspheres.

During World War I, demand for dials, watches, and aircraft instruments painted with Undark surged, and the company expanded operations considerably. oB*654VuG}k{6|}.O-bcDg{/>`&d}/s(7yeO}{zucWx AA8wQ,]KW+vx2\vn~0AUfUkqa..}rCTX'wnc?Cgg7kT}UZF51Y7]3b*@itILyBfC(wlM^W#:llNm,l)b. [3], The company struggled after World War I: the loss of military contracts sharply reduced demand for luminescent paint and dials, and in 1922, high-grade ore was discovered in Katanga, driving all U.S. suppliers out of business except U.S. Radium and the Standard Chemical Company. trans by Alfson, Marymitter Documentation Compiled After.
