Rutherfordium Element Facts


Rutherfordium was made using the U300 cyclotron in Dubna, Russia. This is part of the more recent U400, used in the first ever synthesis of flerovium and livermorium. Image by Jim Roberto, Oak Ridge National Laboratory.

Discovery of Rutherfordium

Rutherfordium may first have been synthesized in 1964 when a team of scientists at Dubna, Russia bombarded plutonium with neon ions.

The discovery was not universally accepted and the synthesis was repeated at Dubna in 1966, and this is generally accepted as the discovery date of Rutherfordium.

The element is named after physicist and chemist Lord Ernest Rutherford, who is known as the father of nuclear physics.

Rutherfordium is radioactive

Rutherfordium is radioactive.

Appearance and Characteristics

Harmful effects:

Rutherfordium is harmful due to its radioactivity.


Rutherfordium is a synthetic radioactive metal created by nuclear bombardment. It has only been produced in miniscule amounts. It is expected to have similar characteristics to hafnium and zirconium.

Uses of Rutherfordium

Rutherfordium is of research interest only.

Abundance and Isotopes

Abundance earth’s crust: nil

Abundance solar system: nil

Cost, pure: $ per 100g

Cost, bulk: $ per 100g

Source: Rutherfordium is a synthetic radioactive metal, created by nuclear bombardment, and has only been produced in tiny amounts. Rutherfordium can be made by bombarding plutonium-242 with accelerated neon ions or by bombarding californium-249 with accelerated carbon ions.

Isotopes: Rutherfordium has 15 isotopes whose half-lives are known, with mass numbers from 253 to 268. None are stable. The most stable isotope is 267Rf, with a half-life of 1.3 hours.
