But, even when the scientific methods of absolute dating are available, this method of dating has not lost its importance, as many a time we have to depend solely on relative dating.
Even when the absolute dates are available, we have to supplement the information with relative dating.
Modern C-14 emits about 15 counts per minute per gram, whereas Carbon-14 which is 5700 years old, emits about 7.5 counts per minute per gram.
The types and forms or shape of these pots and also the antiquities under go evolutionary changes in cource of time, It is further assumed that all living animals derive body material from the plant kingdom, and also exhibit the same proportion of C-14 material.The various methods of relative dating are; This method depends on the common observation that the height of the habitational area increases as the people continue to live at the same place.The deposit thus occurring forms layers depending on the nature of the material brought in by the people inhabiting the area.For example, if the cultural contents of the lower deposit are Mauryan in character, appropriately this deposit may be assigned a date between 400-200 B. Similarly, if the cultural equipment of the upper deposit are of the Sunga period, this deposit has to placed between 200-73 B. Quite often, the archaeologist decided the change of stratum on the basis of the feed of the deposit.In such cases subjective element cannot be ruled out.
In the disintegration process the Carbon-14 returns to nitrogen emitting a beta particle in the process.
