question on Tritium Science and watches. Read the details.? Tritium was once used in some watches to produce fluorescence so that the watch can be read in the dark. If the light intensity is proportional to the activity for tritium, which is the brightness of the clock, compared to its original brightness, when the watch is about 6 years?
If you could give me the procedure how you found it, it would be great! Thank you
According to wikipedia, the half-life of tritium is 4500 days or 12.3 years 4500/365.25 =
From the equation half-life after 6 years, there would be:
(0.5) ^ (6/12.3) = .713, or 71.3% of the tritium originally left.
