Problems with archaeological dating
Astronomical data have been applied in the study of geological ice ages by calculating the curves for major fluctuation of solar radiation.
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.
At that time the radioactive disintegration takes over in an uncompensated manner. only half the C-14 will remain after the half-life period.
In the disintegration process the Carbon-14 returns to nitrogen emitting a beta particle in the process.
Antiquities and potteries of Roman origin were found in association with the finds of Indian origin.
With the aid of these dated imports it was possible to date the associated Indian objects to the first two centuries A. Similarly NBP and PGW has helped in fixing the chronology of numerous sites. Sometimes dates are also obtained with the assistance of astronomy.
