Radiocarbon Dating

The profile of Nancy Athfield


A.  Have you ever picked up a small stone off the ground and wondered how old it was? Chances are, that stone has been around many more years than your own lifetime. Many scientists share this curiosity about the age of inanimate objects like rocks, fossils and precious stones. [Crack IELTS with Rob] Knowing how old an object is can provide valuable information about our prehistoric past. In most societies, human beings have kept track of history through writing. However, scientists are still curious about the world before writing, or even the world before humans. Studying the age of objects is our best way to piece together histories of our pre-historic past. One such method of finding the age of an object is called radiocarbon dating. This method can find the age of an object based on the kind of particles and atoms that are found inside of the object. Depending on what elements the object is composed of, radiocarbon can be a reliable way to find an object’s age. Q1One famous specialist in this method is the researcher Nancy Athfield. Athfield studied the ancient remains found in the country of Cambodia. Many prehistoric remains were discovered by the local people of Cambodia. Q2These objects were thought to belong to some of the original groups of humans that first came to the country of Cambodia. The remains had never been scientifically studied, so Nancy was greatly intrigued by the opportunity to use modern methods to discover the true age of these ancient objects.


B.   Athfield Q3had this unique opportunity because her team, comprised of scientists and filmmakers, were in Cambodia working on a documentary. The team was trying to discover evidence to prove a controversial claim in history: that Cambodia was the resting place for the famous royal family of Angkor. [Crack IELTS with Rob] At that time, written records and historic accounts conflicted on the true resting place. Many people across the world disagreed over where the final resting place was. For the first time, Q4Athfield and her team had a chance to use radiocarbon dating to find new evidence. They had a chance to solve the historic mystery that many had been arguing over for years.


C.   Athfield and her team conducted radiocarbon dating of many of the ancient objects found in the historic site of Angkor Wat. Nancy found the history of Angkor went back to as early as 1620. Q7According to historic records, the remains of the Angkor royal family were much younger than that, so this evidence cast a lot of doubt as to the status of the ancient remains. [Crack IELTS with Rob] The research ultimately raised more questions. If the remains were not of the royal family, then whose remains were being kept in the ancient site? Athfield’s team left Cambodia with more questions unanswered. Since Athfield’s team studied the remains, new remains have been unearthed at the ancient site of Angkor Wat, so it is possible that these new remains could be the true remains of the royal family. Nancy wished to come back to continue her research one day.


D.   In her early years, the career of Athfield was very unconventional. She didn’t start her career as a scientist. In the beginning, she would take any kind of job to pay her bills. Most of them were low-paying jobs or brief Community service opportunities. She worked often but didn’t know what path she would ultimately take. [Crack IELTS with Rob] But eventually, her friend suggested that Athfield invests in getting a degree. Q8The friend recommended that Athfield attend a nearby university. Though doubtful of her own qualifications, she applied and was eventually accepted by the school. It was there that she met Willard Libby, the inventor of radiocarbon dating. She took his class and soon had the opportunity to complete hands-on research. She soon realised that science was her passion. After graduation, she quickly found a job in a research institution.


E.   After college, Athfield’s career in science blossomed. She eventually married, and her husband landed a job at the prestigious organisation GNN. Athfield joined her husband in the same organisation, and she became a lab manager in the institution. Q9She earned her PhD in scientific research, and completed her studies on a kind of rat when it first appeared in New Zealand. [Crack IELTS with Rob] There, she created original research and found many flaws in the methods being used in New Zealand laboratories. Q10Her research showed that the subject’s diet led to the fault in the earlier research. She was seen as an expert by her peers in New Zealand, and her opinion and expertise were widely respected. She had come a long way from her old days of working odd jobs. It seemed that Athfield’s career was finally taking off.


F.   But Athfield’s interest in scientific laboratories wasn’t her only interest. She didn’t settle down in New Zealand. Instead, she expanded her areas of expertise. Q11Athfield eventually joined the field of Anthropology, the study of human societies, and became a well-qualified archaeologist. It was during her blossoming career as an archaeologist that Athfield became involved with the famous Cambodia project. [Crack IELTS with Rob] Even as the filmmakers ran out of funding and left Cambodia, Athfield continued to stay and continue her research.


G.   In 2003, Q12the film was finished in uncertain conclusions, but Nancy continued her research on the ancient ruins of Angkor Wat. This research was not always easy. Her research was often delayed by lack of funding, and government paperwork. Despite her struggles, she committed to finishing her research. Q13Finally, she made a breakthrough. Using radiocarbon dating, Athfield completed a database for the materials found in Cambodia. [Crack IELTS with Rob] As a newcomer to Cambodia, she lacked a complete knowledge of Cambodian geology, which made this feat even more difficult. Through steady determination and ingenuity, Athfield finally completed the database. Though many did not believe she could finish, her research now remains an influential and tremendous contribution to geological sciences in Cambodia. In the future, radiocarbon dating continues to be a valuable research skill. Athfield will be remembered as one of the first to bring this scientific method to the study of the ancient ruins of Angkor Wat.
