"Radiometric dating still reliable (again), research shows." Science Daily.
But even he “realized that there probably would be variation”, says Christopher Bronk Ramsey, a geochronologist at the University of Oxford, UK, who led the latest work, published today in Science.Researchers from NIST and Purdue tested this by comparing radioactive gold-198 in two shapes, spheres and thin foils, with the same mass and activity. The team reasoned that if neutrinos are affecting the decay rate, the atoms in the spheres should decay more slowly than the atoms in the foil because the neutrinos emitted by the atoms in the spheres would have a greater chance of interacting with their neighboring atoms.The maximum neutrino flux in the sample in their experiments was several times greater than the flux of neutrinos from the sun.Donations to Student News Daily are tax deductible and greatly appreciated.Recent puzzling observations of tiny variations in nuclear decay rates have led some to question the science behind carbon-14 dating and similar techniques.
