Definition of 'radiocarbon'. radiocarbon (reÉªdioÊkÉËÊ³bÉn ) also radio carbon. Radiocarbon is a type of carbon which is radioactive, and which therefore breaks up slowly at a regular rate. Its presence in an object can be measured in order to find out how old the object is.
Radiometric dating (often called radioactive dating) is a technique used to date materials such as rocks or carbon, in which trace radioactive impurities were selectively incorporated when they formed.otassium-40 has a half-life of 1.3 billion years, and so this method is applicable to the oldest rocks. Radioactive potassium-40 is common in micas, feldspars, and hornblendes, though the closure temperature is fairly low in these materials, about 350 Â°C (mica) to 500 Â°C (hornblende).
