The glowing of the watch dials in the dark because of the light emitted by phosphor when struck by the beta particle formed from the tritium decay is given. The percent dimming of the watch dial in a 50 year old watch if the light given off is assumed to be directly proportional to the amount of tritium is to be calculated. Concept introduction: The radioactive decay is always a first order reaction and the half life of a nuclear reaction is the time required by a radioactive element to decay half of its initial concentration. To determine: The percent dimming of the given watch dial in a 50 year old watch if the light given off is assumed to be directly proportional to the amount of tritium.
