Ra-226 has been used in numerous applications following its discovery over 100 years ago. 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.

The rate of radioactive decomposition corresponding to 3.7 x 10^10 disintegrations per second is called a curie. What weight (in grams) of Ra-226, with half-life period of 1620 y, will be required to yield 1 millicurie of radiation? 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.

From the mass of Ra 226, one can determine the number of atoms. Then one may use the definition of activity, which is: A = λN, where λ is the decay constant, and N is the number of atoms. λ can be determined from the half-life, if it is not already know.
