Assume you have such a watch. if a minimum of 18.0% of the original tritium is needed to read the dial in dark places, for how many years could you read the time at night? assume first-order kinetics.

Given that the half life of 3H is 12.3 years.

The amount of substance left of a radioactive substance with half life of after t years is given by



Therefore, the number of years it will take for 18% of the original tritinum to remain is given by



Therefore, the number of years that the time could be read at night is 30.4 years.

Idon’t even know the answer hehehehe

Ikr they be playing
