Best suited to the carbon 14 dating technique

The age we come up with is around 50 000 years old.The reason it isn't 1 million year old is because the half-life of 14-C is about 5 730 years, which means after about 50 000 years there is no more 14-C to measure, hence the limit of that dating technique is about 50 000 years.Knowing that small concentrations of collagen can attract contamination, they compared precision Accelerator Mass Spectrometry (AMS) tests of collagen and bioapatite (hard carbonate bone mineral) with conventional counting methods of large bone fragments from the same dinosaurs. Mary Schweitzer, associate professor of marine, earth, and atmospheric sciences at North Carolina State University, surprised scientists in 2005 when she reported finding soft tissue in dinosaur bones.These, together with many other remarkable concordances between samples from different fossils, geographic regions and stratigraphic positions make random contamination as origin of the C-14 unlikely". She started a firestorm of controversy in 20 when she reported that she had sequenced proteins in the dinosaur bone.This is then transformed into isotopic ratios and then used to date the material.

Another example, you may want to use (carbon-14) to date an old object.

Lets say the object is a million years old (but as the scientist measuring this object we don't know that) and we go to measure it using the 14-C method.

Researchers have found a reason for the puzzling survival of soft tissue and collagen in dinosaur bones - the bones are younger than anyone ever guessed.

Carbon-14 (C-14) dating of multiple samples of bone from 8 dinosaurs found in Texas, Alaska, Colorado, and Montana revealed that they are only 22,000 to 39,000 years old.

This low concentration will mean your counting statistics will not be as robust and may result in decreased precision.

  1. i have a problem with the updating view process(that i can see in the notes log.nsf) because lotus notes server start to updating all view of all database during staff working time and i want that it start for example at pm of every day when all user are not working with notes, because Updating view 'aaa' process reduce a lot server performance and database works slowly).
