This is why it is such a big concern when a nuclear submarine sinks... (By the way, you are mostly Carbon-12, which is not radioactive.
Eventually, the salt water will eat through the steel and release the Plutonium (which, as you know, is quite lethal.) They usually talk about either trying to raise the sub or encase it in concrete where it rests. That's why we are called "Carbon-based life forms." Man, I've really watched too much Star Trek.)Scientists use Carbon-14 to make a guess at how old some things are -- things that used to be alive like people, animals, wood and natural cloths. Anyway, they make an estimate of how much Carbon-14 would have been in the thing when it died...

Most radioisotopes do not decay directly to a stable state, but rather undergo a series of decays until eventually a stable isotope is reached.
The nucleus consists of protons (p) and neutrons (n), and is extremely small. ) In some types of atom, the nucleus is unstable, and will decay into a more stable atom. It's not the same as what happens in a nuclear power station (where neutrons whizz around and hit uranium nuclei, causing them to split).
That's what we've believed for some time - but recent research makes us wonder if this is true after all.
These ions are accelerated in an electric field through collimating slits and subject to a magnetic field which causes the ions to follow a curved path. By adjustment of the strength of the magnetic field and suitable placement of an ion collector, the different isotopes can be measured with precision.
There are some things that affect these measurements.
The alpha particle leaves the scene at a high velocity -- perhaps 10,000 miles per second (16,000 km/sec).
If you were looking at an individual americium-241 atom, it would be impossible to predict when it would throw off an alpha particle.
After the second half-life has elapsed, yet another 50% of the remaining parent isotope will decay into daughter isotopes, and so on.
For all practical purposes, the original isotope is considered extinct after 6 half-life intervals. A small portion of a meteorite is vaporized in the device forming ions.
The time it takes for a single parent atom to decay to an atom of its daughter isotope can vary widely, not only between different parent-daughter pairs, but also randomly between identical pairings of parent and daughter isotopes.
