What does RA 228 decay into?
beta particle
Radium-228 has a half-life of (5.75 years) and decays by emitting a beta particle.
What happens when Radium-226 decays?
Radium-226 decays by alpha particle radiation to an inert gas, radon-222, which also decays by alpha particle radiation. Due to the short half-life of radon -222, 3.8 days, there is a high probability it will decay in the body when breathed in, emitting alpha particle radiation in the body.
How does radium-228 decay?
Radium-228 is a radioactive decay product in the thorium-232 decay series. Radium-226 decays slowly (half-life of 1,600 years) by emitting an alpha particle. Radium-228 has a much shorter half-life (5.8 years) and decays by emitting a beta particle.
What is the half-life of 226ra?
1600 years
The longest lived, and most common, isotope of radium is 226Ra with a half-life of 1600 years.
What is the difference between RA 226 and RA 228?
The two most common isotopes of radium are radium- 226 and radium-228. Radium-226 has a long half-life (1,600 years) compared to that of radium-228 (5.75 years). Radium-226 decays by emitting the nucleus of a helium atom (alpha particle), whereas radium-228 emits an electron (beta particle).
What does Rn decay into?
It is radioactive with a half-life of 3.8 days, decaying by the emission of alpha particles to polonium, bismuth, and lead in successive steps.
What element is produced from by the decay of radium-226?
Radon
Radon. Radioactive decay of natural radium-226 to the gas radon-222 occurs within the water column and results in a loss of radon from the surface mixed layer to the atmosphere.
What is the difference between radium-226 and radium 228?
Radium-226 has a long half-life (1,600 years) compared to that of radium-228 (5.75 years). A half-life is the time required for half of the initial amount of the radionuclide to decay. Radium-226 decays by emitting the nucleus of a helium atom (alpha particle), whereas radium-228 emits an electron (beta particle).
What is uranium 234 used for?
Uranium-234 is one of the three isotopes of uranium and the last isotope that still occurs in nature. Uranium-234 is used in the making of nuclear weapons and nuclear fuels.
How did Marie Curie extract radium?
Marie extracted pure radium salts from pitchblende, a highly radioactive ore obtained from mines in Bohemia. The extraction required tons of the substance, which she dissolved in cauldrons of acid before obtaining barium sulphate and other alkalines, which she then purified and converted into chlorides.
