27 Feb : Radio carbon dating was made possible

Science has many aspects which don't look important but they actually are. One such thing is radiocarbon dating. It's an interesting concept, read here.

You must have read or heard about archaeologists digging deep and coming across some 5,000 years old piece of wood, or a 2000 year old painting, or a mummy etc. Now how these archaeologists or scientists find the age of these ancient things ? It’s easy for them because of radio carbon dating.

It is a method for determining the age of an object containing organic material. by using the properties of a radioactive isotope of carbon – Carbon 14. 

Carbon 14 was discovered today in 1940 by Martin Kamen and Sam Ruben. It is a long-lived naturally occurring radioactive carbon isotope of mass 14, used in carbon dating and as a tracer in biochemistry.

There are three naturally occurring isotopes of carbon on Earth: 99% of the carbon is carbon-12, 1% is carbon-13, and carbon-14 occurs in trace amounts. This isotope of carbon which has carbon in trace amounts is used for determining the age of an object containing organic material.

विज्ञान में कई चीज़ें ऐसी हैं जिसका आम आदमी से सीधे-सीधे कोई लेना-देना नहीं होता है। लेकिन आम जनजीवन में इसका असर बहुत होता है। कुछ ऐसी ही चीज़ है Radiocarbon dating। 1940 में आज Martin Kamen और Sam Ruben ने carbon-14 की खोज की थी। इसके ज़रिये radiocarbon dating संभव हो पाई। Radiocarbon dating का इस्तेमाल किसी organic material की उम्र जानने के लिए किया जाता है।
