Radiocarbon dating cost
Radiocarbon dating: radioactive carbon decays to nitrogen with a half-life of 5730 years.
In dead material, the decayed 14C is not replaced and its concentration in the object decreases slowly.
The Accelerator Mass Spectrometry technique, however, enables one to use small amount of samples and determine the date precisely within one hour, which radioactive-dating technique would have taken few years.
The Rs 10-crore national facility will come up at Mumbai University’s Kalina campus.
"For many years, people have tried to do transplantation of cartilage and it's been very, very difficult," said Kjaer.
The facility, known as Accelerator Mass Spectrometry, will be useful in dating miniscule samples from objects of archaeological significance.Further, we estimated how many samples India needs to carbon-date.We came to the conclusion that even if we check 137 samples everyday, our facility will have to function 24 hours for two years at a stretch,” said Dushyant C Kothari, in-charge director of Mumbai University’s Centre for Nanosciences and Nanotechnology, where the facility is being established.Besides its importance from the archaeological and astronomy-archaeological points of view, the facility is critical for geologists and can also be used for pharmaceutical applications in drug development.
“We can use the facility to check when sediments of lakes were created and subsequently gauge the past geological events on the earth,” said Kothari.
"Once you have a damaged cartilage, one should not have too much hope of getting a renewal of it." Researchers have debated whether cartilage, the tissue lining the surface of joints, regenerates or remains "fixed" throughout life, and little is known about the effects of joint diseases on cartilage turnover.
