The spectrum will show a gamma-ray at 1274.5 keV, an annihilation peak at 511 keV (from the b +) and probably x-rays from the electron capture. Sodium (Na) 22 Radioactive Isotope Decay Calculator Online radioactive decay calculator that allows you to find out the radioactivity decay in Sodium (Na) 22. Note: The calculation of radioactivity in minerals is based on certain assumptions. Sodium (Na) 22 Isotope Radioactivity Decay Calculation Na-22 disintegrates predominantly to the 1275 keV level of Ne-22 . A very small fraction (0,056 %) disintegrates to the ground state of Ne-22.

Mar 8, 2012 Radioactive source (Na-22)Sodium-22 is the radioactive source which has 11 protonsAnd 11 neutrons and by beta plus it is decay to Neon-22.

All energies are given in keV. Normally there are energies listed with an intensity ≥ 1 %. Radiation Type .

You may also back decay sources to find out the original activity (or for any date), knowing the current activity. If the isotope that you wish to decay is not on the drop down list, check the 'not listed' check-box and manually enter the isotope name and its half-life to perform the calculation.

May 7, 2015 Figure 8: Unstable elements such as uranium 238 decay over time, These isotopes, such as 56Ni, 22Na, 44Ti, 27Al, decay into 56Fe, 22Ne, Gamma Decay, Spontaneous Fission, Neutron-Rich Versus Neutron-Poor Nuclides emission is more often observed in the lighter nuclides, such as 22Na . Gamma spectrum of Sodium 22 recorded with Gammaspectacular and PRA the annihilation gammas that are produced when 22Na undergoes beta+ decay. For those needing portability, Rad Pro for Desktop works with Windows 8.1/10 tablets. Will not work with Surface tablets running Windows RT. Actinium (Ac) An 8.00 gram sample of a radioisotope decays to a sample of 0.25 grams after 22. Compared to 37K, the isotope 42K has a. (1) shorter half-life and the same characteristics and you will make a Fermi-Kurie plot of the Na22 beta spectrum to demonstrate Fermi's theory of beta decay and confirm the small mass of the.
