 If a sample of cesium-137 is stored in Yucca Mountain, how much time must elapse until only 1/32 of the original sample remains unchanged?

In living organisms, the ratio of naturally occurring isotopes of Carbon, C-12 to C-13 to C-14, is fairly consistent. When an organism such as a Willy mammoths died, it stopped taking in carbon, and the amount of C-14 present in the mammoth began to decrease. Identify the type of nuclear reaction that caused the amount of C-14 in the Woolly mammoth to decrease after the organism died?

 Illuminated EXIT signs are used in public buildings such as schools. If it is green, it may contain tritium-hydrogen-3. Tritium is a gas sealed in glass tubes. The emissions from the decay of the tritium gas cause a coating on the inside of the tubes to glow. 

Complete the nuclear equation below for the radioactive decay of tritium, by writing a notation for the missing product.

Determine the fraction of the original sample of tritium (half-life of 12.33 years) that remains unchanged after 24.62 years.
