A new highly sensitive technique is proposed to estimate the age of ancient bones by the specific activity of 226Ra, which is determined by the registration of 222Rn α–particles using a CR-39 track detector in an isolated chamber. Comparison of sp

The vertical activity concentration distributions of the radium isotopes, 226Ra and 228Ra, which are useful as radiotracers, were obtained for the first time in the western Subarctic Pacific Gyre (WSAG). It was possible to detect short-lived 228Ra pr

Over the course of time, radioactive applications have changed from miracle cures to a material that is treated with caution in public perception. As a Swiss company, which has always been working with radioactive materials, RC Tritec is an interesti
