Rutherford (unit) unit for activity, the rutherford became obsolete, and it is no longer commonly used. The following table shows radiation quantities in SI and non-SI units: Rutherford (unit) The rutherford (symbol Rd) is a non-SI unit of radioactive decay. 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, and one becquerel equals one microrutherford. One rutherford is equivalent to 2.703 × 10 curie. The unit was introduced in 1946. It was named after British/New Zealand physicist and Nobel laureate Lord Ernest Rutherford (Nobel
Comparison of Chernobyl and other radioactivity releases to the inverse square law the dose suffered by members of the general public tends to be very small. Also, very little environmental contamination normally occurs as a result of these accidents. For instance, at Sarov the radioactivity remained confined to within the actinide metal objects which were part of the experimental system, according to the IAEA report (2001). Even the SL-1 accident (meltdown of experimental nuclear reactor in Idaho, 1961) failed to release much radioactivity outside the building in which it occurred.
