One example of this is uranium (atomic number 92) decaying into thorium (atomic number 90). A parent isotope is one that undergoes decay to form a daughter isotope. Decay stages are referred to by their relationship to previous or subsequent stages.

Most radioisotopes do not decay directly to a stable state, but rather undergo a series of decays until eventually a stable isotope is reached.

List of patched versions here There are proof of concepts available here.The sediment samples must remain totally undisturbed during sampling to obtain the best possible dating.Subsequently, they are cut into slices of approximately 1 cm and dried, whereupon the content of dry matter and possibly the loss on ignition are determined.A race condition was found in the way the Linux kernel's memory subsystem handled the copy-on-write (COW) breakage of private read-only memory mappings.All the information we have so far is included in this page.
