Rutherford (unit)
The rutherford (symbol Rd), was named after British physicist and Nobel laureate Lord Ernest Rutherford (Nobel Prize-1908).[1] It is defined as the activity of a quantity of radioactive material in which one million nuclei decay per second. It is therefore equivalent to one megabecquerel. Becquerel being the SI unit for activity, it has been rendered obsolete and is not commonly used.
One rutherford is equivalent to 2.703 × 10−5 curie.
