Radiocarbon dating of the iceman otzi with accelerator mass spectrometry
In the 19th century it was common for Western tourists and scholars who journeyed to Egypt to bring home mummies, coffins, and other artefacts as souvenirs, Dr Sowada said.
Together with the plaster samples and CT scans, the carbon dating will help us nail the date and build a story about the origins of this mummy.
The man's body was recovered and pieces of tissue were studied for their C content by accelerator mass spectroscopy.
The best estimate from this dating technique says the man lived between 33 BC. From the ratio, the time since the formation of the rock can be calculated.
The boat of a pharaoh was discovered in a sealed crypt and reassembled in a museum near the pyramids (see Fig. The age of our galaxy and earth also can be estimated using radioactive dating.
Using the decays of uranium and thorium, our galaxy has been found to be between 10 and 20 billion years old and the earth has been found to be 4.6 billion years old. Within experimental error, this estimate agrees with the 15 billion year estimate of the age of the Universe.
