Subsequent irradiation, for example if an x-ray is taken, can affect accuracy, as will the "annual dose" of radiation a buried object has received from the surrounding soil.
Because organic materials are present in only a limited number of sites many such occurrences are not amenable to radiocarbon dating and often luminescence provides the only alternative.
Using a range of approaches it often possible to obtain dates from either ceramics or soil and in the former case luminescence has an advantage over radiocarbon since it can directly date the object of interest rather than associated material. Feathers has shown that luminescence may be as accurate as radiocarbon.
The typical range for burnt stone or sediment is from about 100 to 500,000 years for luminescence dating methods and 1ka to 1000ka for ESR dating.
The error limits on the dates obtained are typically in the range of 5 to 10%.
