Radioactive isotope in ice core record reflects solar activity over 600 years

Washington, July 4 (ANI): Scientists have analyzed Beryllium-10, a radioactive isotope, found from the NGRIP ice core, Greenland, which reflects solar activity over the past 600 years.

Beryllium-10, a radioactive isotope, is produced in cosmic ray showers.

Because stronger solar activity deflects cosmic rays away from Earth, low [...]
