Does Radium 226 gives of alphabetagamma radiation?
After alpha disintegration radium-226 become radon-222. Another answer: All of the isotopes of Radium are radioactive. When they decay, they emit radiation and form new radioactive elements. Isotopes of Radium decay into different isotopes of Radon. Radium-226 will decay into Radon-222, and Radium-228 goes through several decays to Radium-224 before forming Radon-220. The entire process stops when the last decay process yields stable Lead.
Radium-226 is radioactive and presents a health hazard. Before radiation was understood clearly, radium was put into a number of consumable and personal care products. It used to be used on the hands of clocks and on the dials of aircraft instruments because it "glows in the dark" (is luminescent, or self-luminous). It is used now as a radioactive source in cancer treatment. Radium is actually used to generate radon, which is a radioactive daughter…
How many milligrams of a 15.0 mg sample of radium-226 remain after 6396 years if the half-life of radium-226 is 1599?
Radium-226 has a half-life of 1620 years. How much of a 24 gram sample will remain after 4860 years?
The 4860 years represents three half-lives of radium-226. (It has a half-life of 1620 years, as stated. After one half-life, 12 grams of the original sample will remain. After another half-life, 6 grams will remain. (That's 3240 years gone by.) Finally, after a third half-life goes by (the 4860 years), 3 grams of the original 24 gram sample of radium-226 will remain.
