Scientists have developed a new method for detecting gold in the earth’s crust using X-rays. The technique, called Gamma Activation Analysis (GAA), works by bombarding rock samples with high-energy gamma rays, making even the smallest traces of gold visible to a highly sensitive detector. The GAA is about two to three times more effective than traditional methods, and experts estimate that it could bring in an additional half a billion dollars in profits each year. Previously, rock samples had to be heated to 1,200 degrees Celsius to separate the individual components before experts could determine the gold content. With the GAA, the gold content can be determined on-site within minutes.
The new method has already shown promising results, and scientists are already working on modifications to expand its capabilities. In addition to gold, the GAA could also be used to detect other metals such as lead, copper, silver, and tin. The device is also expected to become smaller and more compact, making it easier to use directly on-site.
This breakthrough in gold detection is significant because gold is a rare and valuable resource, and the search for it is often difficult and time-consuming. The GAA offers a faster and more accurate way to detect gold, which could lead to increased profits for mining companies and a more efficient use of resources. The development of this new technology is a testament to the power of scientific innovation and its potential to transform industries and improve our lives.
