You forgot to say that isotope is.
Ozone is decayed back to oxygen. It depends on how the ozone is being converted.
It takes 100 years for a battery to decompose.
I'm Assuming you mean how long does it take for a tuna fish can to decay? Well the time wil vary depending on the temperature of the water, the mineral content and salinity of the water. If you use fresh tap water it will take a long time. Most tap water is balanced especially if you have a water softner. Now river water will take about a year or more in the mountains of california. But in the ocean it may only take a few months. It is all dependent on the impurities in the water.
The decay rate of atoms is typically quantified by a half-life, which is the time it takes for half of the original atoms to decay. If we assume a constant decay rate, we can estimate that it takes approximately 3 half-lives for 75 of the original 100 silver atoms to decay. If the half-life of the silver isotope is 1 hour, then it would take approximately 3 hours for 75 of the atoms to decay.
If a human is buried in the ground in a quality coffin, it could take as much as 50 years for the body to decompose. If the body is buried in a cheap casket, decomposition and exposed to the elements, decomposition happens very quickly.
a while
It takes hundreds of years.
about 3-4 months

Decay starts immediately upon death. Decay happens because the body's cells start to die. When the cells die, they exit the body, and dissolve into the ground. The soft tissues cells die first.
The fustion will take place so long as the decay time for isotopes which is ...not stable is over.
a few months
It will take two half-lives or about 60.34 years for three-fourths of a Cs-137 sample to decay.
it takes 1 day 17 hours and 29 minutes for orange juice to rot or decay
10.76 days
It takes about 0.89 ms
