What are two limitations of radiocarbon dating
{"Image DocumentName": "Limitations to Radioactive Carbon Dating", "Image ImageDescription": "Using this technique, almost any sample of organic material can be ABSOLUTELY dated. There are a number of limitations, however: First, the size of the archaeological sample is important. Larger samples are better, because purification and distillation remove some matter. Second, great care must be taken in collecting and packing samples to avoid contamination by more recent carbon. Also, the sample should be carefully examined to determine that a carbon sample location was not contaminated by carbon from a later or an earlier period.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
