The 222 Rn activity of the GW, however, distinctly exceeds the 222 Rn concentration in the Aral Sea (10 mBq/l), in principle, making 222 Rn a sensitive tracer for the inflow of GW.

Most of the significant gamma radiation from 226 Ra decay comes from the radioactive progeny 214 Pb and its daughter, 214 Bi. These are produced following the decay of 226 Ra to 222 Rn, which then decays to 214 Pb. Since 222 Rn is a gas it will escape, to varying degrees, from unsealed sources, and the gamma radiation from the 214 Pb and 214 Bi The NEUTRAL atomic mass of the nuclide Radium(226,88) = 226.025403 u. The neutral atomic mass of Radon Rn(222,86) = 222.017571 u The mass of the neutral Helium-4 = 4.002603 u The difference in mass between the orinal nucleus Radium(226,88) and the decay final product Rn(222,86) and He(4,2), called the mass defect is Δm = 226.025403 u - (222.017571 u + 4.002603 u ) = 0.005229 u . 222 Rn: 4,87070(25) MeV: Die Abbildung [Radium-226 decay chain] zeigt die vom Ra-226 ausgehende radiaktive Zerfallskette einschließlich der selteneren Answer to: Complete the following equation.

Since radium The best way to protect yourself and your family is to test your home for radon. In a sealed source these daughter products would be in secular equilibrium with the parent radium atoms.
