1/2 of the 1/2 = 1/4 the original sample.
You have 100 g of radioactive C-14. The half-life of C-14 is 5730 years.
A sample of 3x107 Radon atoms are trapped
in a basement that is sealed. The half-life of
Radon is 3.83 days. How many radon atoms
are left after 31 days?
In nuclear reactors the heat generated by the reaction is used to produce steam that turns a turbine connected to a generator.
