Yes, sufficient care is taken in the selection of the original sample.

Similar care is needed in the selection of the dating series (K-Ar, Rb-Sr, etc), for not all minerals are equally suitable for dating.

The rock must not have suffered any metamorphism or other change, which could re-distribute the elements in a new matrix.

The care in the laboratory is of a 'clean room' standard, and techniques must exclude any possibility of contamination due to handling. e.g. borosilicate glass must be used rather than the common lime soda glass.

With care dating using K/Ar may have an accuracy of a few percent.

Have a crack at K-Ar Dating in a reference such as wikipedia. This will give an idea of the sophistication of the method and its background required.

Yes, it is quite accurate but only if the procedure is carried out correctly. One way to prove the accuracy of radiometric dating is cross referencing different samples. The age of the Earth has been determined as approximately 4.5 billion years old, and this is in good agreement with the age of moon rocks and meteorites.

(The Clock was Reset to Zero)suggests that at the time rocks forms, the amount of parent and daughter isotopes are known or can be calculated... daughter products develop as the rock becomes older... radiometric ages that appear older than they should are explained by saying the clock was not reset. contradicted by evidence that suggests the ratio of parent and daughter material in volcanic rock varies and is unpredictable...(Closed System) suggests that the material being tested has not gained or lost parent or daughter material since it formed. radiometric ages that appear older or younger than they should are explained by saying the system was not closed. contradicted by evidence that samples are often not isolated and are affected by the environment.

Radio Carbon dating has been used for many years, and the accuracy has been improved by new techniques and equipment- but the error (plus or minus) is still measured in years- not days or months. So the answer depends on how you define accuracy.

Isotopic (commonly called radiometric dating) is extremely useful in finding the actual age of rock, particularly when a sample contains more than one isotope that can be used to determine the amount of radioactive decay that has occurred. There is some unavoidable inaccuracy present in that the formation or cooling of igneous rock from magma that contains useful isotopes can be a process that takes a widely varying amount of time, sometimes a million years or more.

On the lighter side

Boy atoms and girl atoms have the same chance of finding 'the one' as any one of us humans. There will be one other radioactive isotope which is perfect for another, and to find this we use radioactive dating. Common locations for radioactive dates are the cinema, theatre or the ozone layer, and quite often end in what we call 'bonding', a euphemism for atoms 'hooking up'.

No. Datings can be made to a +/- that varies according to the length of time dated.

For millions of years that could mean to a +/- of several thousand years. For thousands, that would be +/- hundreds

Why doesn't radiometric dating produce exact results?

No because it impossible to show the exact result


Does radioactive dating produce exact results?

No, radioactive dating does not produce exact results. No form of radioactive dating produces exact results. But results can be gotten that are surprisingly accurate. As a "for instance" we might look at uranium-lead dating. This dating method can deliver results accurate to a million or two years in a billion years. That's about 0.1 to 0.2 % or so.


Is it possible that radiomatic dating produces exact results?

Unlikely - too many variables.


Does radioactive dating allow us to find relative or absolute age?

Absolute dating of rock is achieved by radiometric dating techniques. Relative dating is achieved by determining the position of rock in strata, and the appearance of certain index fossils. Relative dating was a precursor to absolute dating. Before absolute dating techniques were discovered, the age of a rock was a guesstimate at best. Radioactive dating allows us to find an approximate date. So if something is dated about a thousand years ago plus or minus a hundred years the object may be from sometime between 1,000 and 1,200 A.D.


What is the exact age f the earth right now?

No one can tell you exactly of course. But modern geologists and geophysicists consider the age of the Earth to be around 4.54 billion years old. This age has been determined by radiometric age dating of meteorite material and is consistent with the ages of the oldest-known terrestrial and lunar samples.


Radiometric dating or carbon dating which is more accurate?

Carbon dating (also called radiocarbon dating) is a very useful archeological tool, but it does have its limitations. Dates derived from carbon dating aren't exact, and they always have a margin of error. For example, a particular object that has been dated might a radiocarbon age of 4500 years, plus or minus 30 years. The margin of error depends on the object, but for samples younger than 10,000 years, the uncertainty is usually at most 40 years. For older samples, the uncertainty period can be several centuries. The reason that carbon dating isn't exact is due to two reasons. First of all, our instruments used to detect the amount of radioactivity in samples aren't perfect. Second of all, in the real world, many events can influence and distort the amount of Carbon-14 present in a sample. Events such as volcanic eruptions can increase or reduce the amount of Carbon-14. Scientists need to account for this with a margin of error. In addition, carbon 14 decays with a half life of about 5,700 years and, even with good quality samples, dating can only go back to around 60,000 years. To date anything older than that, scientists need to rely upon other dating methods, like relying upon other isotopes such as potassium and argon. See the links below for more information. The first one describes the process of carbon dating in general, and the second one discusses the accuracy of carbon dating.

What is the difference between relative-age dating and absolute-age dating?

The difference between relative dating and absolute dating is that relative dating is a method of sequencing events in the order in which they happened. Absolute dating is a method of estimating the age of a rock sample in years via radiometric techniques.Short Answer:The term relative dating is distinguished from absolute dating to make it clear that one does not get a specific estimate of the age of an object from relative dating, but one does get such an estimate of true age from absolute dating. There are several techniques employed in both sets of methods. Radiometric dating is one type of absolute dating.Long Answer:Sciences such as geology, Paleontology and archeology are very interested in identifying the age of objects found and these scientists sometimes use both relative dating or absolute dating to characterize the age of the objects they study.Before radiometric dating (or other methods of absolute dating like counting tree rings) it was difficult to determine the actual age of an object. Radiometric dating, based on known rates of decay of radioactive isotopes in objects, allows a specific age of an object to be determined to some degree of accuracy.Relative dating is a scientific process of evaluation used to determine the relative order of past events, but does not determine the absolute age of an object. The circumstances of the object may allow one to say that one object is older than another without being able to assign a particular age to the objects. Very often historical evidence is found in layers and older layers are further down that the top layers.For example:If an archaeologist is studying past civilizations, the archaeologist may be able to say that in a particular location the ruins of one civilization were found to have been built on another and so the layers unearthed in an excavation convey the sequence of historical occupations without revealing the actual dates. However, carbon dating is an absolute dating technique that can give an estimate of the actual age of an artifact and thus an estimate of the age of other objects in the same layer. Carbon dating is one example of radiometric dating.Similarly, relative dating is done by paleontologists who find layers of fossils. By deducing which fossils are formed in the sequence of time, the periods when the particular fossilized entities existed can be arranged in order without the actual dates of when the fossils were laid down. The radiometric techniques that give absolute dating estimates are based on radioactive decay of elements such as uranium.For geologists, it is similar. Looking at how rock formations are structured, a geologist may be able to say which rock was developed in which layer in a particular order but not be able to determine that actual geologic age of the layers. Geologists also have radiometric methods for absolute dating based on radioactive decay of certain elements.
