Uncertianty wiht carbon 14 dating

The Olympic sport of biathlon (Figure 1) is a cross-country ski race of 20 km in which the athletes stop on four occasions to shoot 0.57 cm diameter bullets from a .22 caliber rifle at targets.

The sport requires not only great endurance, but exceptional accuracy as the athletes shoot on two occasions from the prone position (lying down) and on two occasions while standing.

It's accuracy has been verified by using C-14 to date artifacts whose age is known historically.

The fluctuation of the amount of C-14 in the atmosphere over time adds a small uncertainty, but contamination by "modern carbon" such as decayed organic matter from soils poses a greater possibility for error. Thomas Seiler, a physicist from Germany, gave the presentation in Singapore.

While the legend of Robin Hood splitting one arrow with another is well-known, it is also unrealistic.

Biathlon targets are purposely sized many times larger than the bullets the athletes shoot to account for the inherent error and uncertainty involved in long distance riflery.

The preferred method of dating dinosaur fossils is with the radiometric dating method.

The size of the sample then required, however, was ~500cm, which would clearly have resulted in an unacceptable amount of damage, and it was not until the development in the 1970s of small gas-counters and accelerator-mass-spectrometry techniques (AMS), requiring samples of only a few square centimetres, that radiocarbon dating of the shroud became a real possibility. The shroud was separated from the backing cloth along its bottom left-hand edge and a strip (~10 mm x 70 mm) was cut from just above the place where a sample was previously removed in 1973 for examination.The theoretical limit for C-14 dating is 100,000 years using AMS, but for practical purposes it is 45,000 to 55,000 years.If dinosaur bones are 65 million years old, there should not be one atom of C-14 left in them.Dinosaurs are not dated with Carbon-14, yet some researchers have claimed that there is still Carbon-14 in the bones. Do these data indicate that a more accurate method needs to be derived?What solutions are available for increasing accuracy of the tests? From the source linked above: Carbon-14 is considered to be a highly reliable dating technique.

Photography of the shroud by Secondo Pia in 1898 indicated that the image resembled a photographic 'negative' and represents the first modern study.
