Sixteen isotopes of radium are known, but only radium-226 (half-life 1,599 years), the most stable of the isotopes, is used commercially. It has a long half life, I believe Ra-226 has a specific activity of 1 Ci/gm, which would be about 10 E10 Bq/Kg if my math is correct. Hard to imagine the need for 1 Kg. Answer to: The half-life period of Ra226 is 1620 years. Calculate the decay rate of Ra226 in alpha particles per gram per second. By signing up, Uranium-238 has half life of 4.51 * 10^9 years Uranium-234 has half life of 2.48 * 10^5 years Thorium-230 has half life of 8.0 * 10^4 years Radium-226 has half life of 1.62 * 10^3 years Lead-210 has half life of 20.4 years.

At the beginning of the 20 th Century, radium was a popular additive in consumer The long-lived radium-226 is found in nature as a result of its continuous formation from uranium-238 decay. Radium thus occurs in all uranium ores, but it is more widely distributed because it… Other articles where Radium-226 is discussed: radium: Occurrence, properties, and uses: …known; their half-lives, except for radium-226 (1,600 years) and radium-228 (5.75 years), are less than a few weeks. Radium-226 (226 Ra) is was the first common radionuclide used in brachytherapy since it’s discovery in 1898.
